Is there a higher analog of "category with all same side inverses is a groupoid"? After executing the above matlab code, we created an array G of decimal numbers. And examples respectively. Now I want to access some rows in each of the cells (for instance in this way F{1:end}(2:2:end,:)) and finally, Convert them into an ordinary array by cell2mat. 4. My proposal (avoid cellfun and just use ismember): does not match the order of the elements, so it returns a match even if the rows elements are in a totally different order. Then we used matlab to find values in the array function. This is a guide to Matlab find value in array. close all; 2022 - EDUCBA. I want to find the indexes of A which contains a specific string from B and i want to repeat that for every element of B. I used the following function to find out the indexes for one element of B at a time. Edit: Theme Copy ValueToFind = {'g' 'h' 'i'}; %Define cell array of values to find in same row l = length (ValueToFind); ca = {'a' 'b' 'c' 10 10; 'c' 'e' 'f' 10 20; 'g' 'h' 'i' 20 10;}; 0 Comments Sign in to comment.
