Check if value exists in array matlab

@Jordan: the answer returned is a logical array (true/false) of the same size as the argument, indicating whether the matrix A contains each of those values (e.g [true, true, false] meaning A contains the values 5 and 7 but not 11). Sep 21, · There is a cell in name of 'CELL'. it is 1* its needed to check being and existing of a specified string in arrays of 'CELL'. so if the string doesn't exist do something.

Asked by MathWorks Support Team. MathWorks Support Team The 'exist' function returns true if a structure with a particular. Dec 28, · hi all, i want to check a number in the array.i have created an array and i want to know that a whether a perticular number belongs to the array or not. is there any inbuild function for "belongs to" in matlab. can anybody help me? Can anyone tell me if there is a way (in MATLAB) to check whether a certain value is equal to any of the values stored within another array? The way I intend to use it is to check whether an element index in one matrix is equal to the values stored in another array (where the stored values are the indices of the elements which meet a certain criteria). I'd really like to know, how would it be possible to check if an element of the cell array,like the above, already exists in Q? Because if it does exist, i do not add anything, but if yes, i had to add this element to the end of Q. How could this check be done properly? Short solutions, if possible of course, would be a little more appreciated. My problem is, how is it possible to check if the first value of each row in the cell array Q, in the example above 0, remains the same? What I would like to achieve, is while the first value is the same, I want to store in another cell array, all the second values. Return 1 if number a exists in vector b otherwise return 0. a = 3; b = [1,2,4]; Returns 0. a = 3; b = [1,2,3]; Returns 1. Locations in B, returned as a vector, matrix, or N-D array. If the 'legacy' flag is not specified, Locb contains the lowest indices to the values (or rows) in B that are found in A. Values of 0 indicate where A is not a member of B. Locb is an array of the same size as A unless you specify the 'rows' flag. Apr 15, · should be zero if there is no value or the index does not exists, this works in C++, C# etc.. Is there any function in Matlab. Like I am accessing every pixel, and its 8 neighbourhood.First post so I'm not sure if this will show up with the correct formatting but how about something like getting the absolute value of subtracting repmat(row vector, n. The description is ambiguous as to what "is an element of array" means for a two element vector, but I assumed that the desired end result is to check if any. Detect object of given MATLAB class or Java class. isappdata, Determine if object has specific application-defined data. iscell, Determine if input is cell array. tests a random 5 by 5 matrix to see if all of its elements are less than Return a logical array which is true where the elements of x are NaN values and false . If you wish to check if a variable exists at all, instead of properties its elements. exist. Check if a variable or file exists. Graphical Interface. As an alternative to the and P-files must be on the MATLAB search path for exist to return the values. Find and match multiple values in a matrix with MATLAB's ismember function . I can check if there is nearest value vector in dataset with vector A. . 12 3 11 1 2 4 ], where B contains respective positions i.e, element 1 is to present at postion 5. In MATLAB, [Lia,Locb] = ismember(a, b) will lead to Lia = [1, 1, a vector containing the highest index in b for each value in a that is a member of b. The output vector contains 0 wherever a is not a member of b. julia> a check whether a newly added row(s) (metabolites) already exists in the sparse matrix. While evaluating the solution, the server encountered an error caused by temporary unavailability of MATLAB Service. Wait a few minutes for the MATLAB . hi all, i want to check a number in the array.i have created an array and i want to know that a whether a perticular number belongs to the array or not. is there any . We can test to see if 15 is in the set represented by X, but to test both of those A = randi(10, [3 4]); %# a random matrix any(A(:)==5) %# does A contain 5? function found in the File Exchange except that it is now built-in to MATLAB.

What from this follows?

It is remarkable

I join. And I have faced it. We can communicate on this theme.

Many thanks how I can thank you?
