# MATLAB find or

### Find logical OR - MATLAB o

• This MATLAB function performs a logical OR of arrays A and B and returns an array containing elements set to either logical 1 (true) or logical 0 (false)
• When you execute find with a relational operation like X>1, it is important to remember that the result of the relational operation is a logical matrix of ones and zeros. For example, the command [row,col,v] = find(X>1) returns a column vector of logical 1 ( true ) values for v
• MATLAB provides its user with a basket of functions, in this article we will understand a powerful function called 'Find'. In its simplest form, find function will return the indices of array X that points to the nonzero elements. If it finds none, the function will return an empty matrix. Syntax of Find Function

Some problems require information about the locations of the array elements that meet a condition rather than their actual values. In this example, you can use the find function to locate all of the elements in A less than 9. I = find (A < 9) I = 8×1 3 6 7 11 14 16 17 22 Or, since it's symmetric: idx = find ( abs (FreqSec-1) <= 0.01, 1, 'last' ) If instead you want the index of the first out-of-range value, use: idx = find ( abs (FreqSec-1) > 0.01, 1, 'first' ) The parameter 'first' is optional, but good for clarity. -g-. Rehman Tabasum on 30 Apr 2021 at 15:18. 0 In polar coordinates, the function is. f ( r, t) = g ( r) h ( t ), where. The global minimum is at r = 0, with objective function 0. The function g ( r) grows approximately linearly in r, with a repeating sawtooth shape. The function h ( t) has two local minima, one of which is global. Code for Generating the Figure

Or type help or str = which (fun1,'in',fun2) returns the path to function fun1 that is called by file fun2 . Use this syntax to determine whether a local function is being called instead of a function on the path. This syntax does not locate nested functions. example. str = which ( ___ ,'-all') returns the results of which to str Basically, I need to extract from this table just the rows where the table1.ID matches 'DHK' and leave the result in another table. This is the code I have just now: cont=0; for p=1:length (table1.ID) ID=table1.ID (p,1); IDstr=ID {1,1}; if strcmp (IDstr,'DHK')==1. cont=cont+1; var1 (cont,1)=table1.var1 (p,1) you can do it this in matlab by the very simple way by using implicit function rem(a,b) , where a is devided by b Find the treasures in MATLAB Central and discover how the community can help you!

If none are found, findreturns an empty, 0-by-1 matrix. In general, find(X)regards Xas X(:), which is the long column vector formed by concatenating the columns of X. indices = find(X, k)or indices = find(X, k, 'first')returns at most the first kindices corresponding to the nonzero entries of X No, you don't. From Matlab documentation: I = FIND(X,K,'first') is the same as I = FIND(X,K). You only need to indicate 'last' if you want it the other way around. - Phonon Aug 12 '11 at 14:2

To find array elements that meet a condition, use find in conjunction with a relational expression. For example, find(X<5) returns the linear indices to the elements in X that are less than 5. To directly find the elements in X that satisfy the condition X<5, use X(X<5).Avoid function calls like X(find(X<5)), which unnecessarily use find on a logical matrix View MATLAB Command. Find the logical AND of two matrices. The result contains logical 1 ( true) only where both matrices contain nonzero values. A = [5 7 0; 0 2 9; 5 0 0] A = 3×3 5 7 0 0 2 9 5 0 0. B = [6 6 0; 1 3 5; -1 0 0] B = 3×3 6 6 0 1 3 5 -1 0 0. A & B. ans = 3x3 logical array 1 1 0 0 1 1 1 0 0

1. You can use find, any, and all along with relational operators to pull out matrix indices in a Matlab array or matrix
2. g languages. Logical OR operator results in true or false based on the inputs that are given to the input signal. They are denoted by | operator (A|B). Please find the below table to understand the working of a logical OR operator in Matlab
3. This MATLAB function performs a logical AND of arrays A and B and returns an array containing elements set to either logical 1 (true) or logical 0 (false)
4. Find string (from table) in cell in matlab. Ask Question Asked 6 years, 3 months ago. Active 2 years, 11 months ago. Viewed 12k times 3. I want to find the location of one string (which I take it from a table) inside of a cell: A is my table, and B is the cell. I have tested : strncmp(A(1,8),B(:,1),1) but it couldn't find the location. I have tested many commands like: ismember,strmatch,find.

This example shows how to filter the elements of an array by applying conditions to the array. For instance, you can examine the even elements in a matrix, find the location of all 0s in a multidimensional array, or replace NaN values in data. You can perform these tasks using a combination of the relational and logical operators MATLAB Function Reference : find. Find indices and values of nonzero elements. Syntax. k = find(x) [i,j] = find(X) [i,j,v] = find(X) Description. k = find(X) returns the indices of the array X that point to nonzero elements. If none is found, find returns an empty matrix. [i,j] = find(X) returns the row and column indices of the nonzero entries in the matrix X. This is often used with sparse. Find and match multiple values in a matrix with MATLAB's ismember function I was preparing some results of an image segmentation algorithm for publishing and needed a way to find all pixels that match a variable set of multiple numbers (e.g. find all elements in the array a that has value 1 or 2) MATLAB Forum - find mit mehreren Bedingungen - Hallo, ich versuche die Funktion find mit mehreren Bedingungen zu verwenden

New MATLAB search path, specified as a character array or string array. MATLAB resolves all path names containing '.', '..', and symbolic links to their target location before adding them to the path.

This may be the reason matlab can see the files in some circumstances and not others (depends on how it tries to access the files). So as said, put your code and excel file in My Document Introduction. This page discusses two different ways of getting MATLAB to find the minimum of a function (versus a data set) - fminbnd and fminsearch.The fminbnd command can find a single independent value that will minimize a one-dimensional function over a specific domain. The fminsearch command can find a single vector of values that will minimize a multi-dimensional function given some.

The primarily objective of this course is to help the leaner to learn quickly the first steps. The prominence here is 'learning by doing. So, the best technique to learn is by trying it yourself. Working through the examples. With MATLAB, you can use a search engine to find the topic you're looking for just by including MATLAB in your query. With Python, you'll usually get better search results if you can be a bit more specific in your query than just including Python. In this section, you'll take the next step to really feeling comfortable with Python by learning about how Python functionality is divided.

Find the index of each letter. While pat matches a sequence of letters having any length, strfind stops as soon as it finds a match and then proceeds to the next match. For example, 'Find' and 'F' are both matches for lettersPattern, since the number of letters for a match is not specified.But strfind matches 'F' first and returns its index.

• Before trying to find all of the roots of this function in MATLAB I think it's worth understanding that it has infinitely many roots due to the inclusion of the $\cos()$ term. Additionally, it is easy to find the roots of the function analytically in this case: The roots are defined by $$\cos(7x)\cdot \exp(-2x^2)\cdot (1-2x^2) = 0.$$ So we have  \cos(7x)=0\text{ or }\exp(-2x^2)=0\text{ or.

If you do not include an extension, xlsread searches for a file with the specified name and a supported Excel extension. xlsread can read data saved in files that are currently open in Excel for Windows If MATLAB ® cannot match the file data to formatSpec, then A can be numeric or a character array. The class of A depends on the values that fscanf reads before it stops processing. count — Number of characters read scalar. Number of characters read, returned as a scalar value. Tips. Format specifiers for the reading functions sscanf and fscanf differ from the formats for the writing. MATLAB will realize that it doesn't have a built-in function named val_port and search the relevant directories for a file named val_port.m, then use the function contained in it. Whenever possible, you should try to create m-files to do your work, since they can easily be re-used Supported File Formats for Import and Export.
