The index of the largest element in a 2D array in matlab

[v,ind]=max(X);
[v1,ind1]=max(max(X));
disp(['The largest element in X is' num2str(v1) ' at (' num2str(ind(ind1)) ',' num2str(ind1) ')']);

i have a folder of image and have a array of indices of the images in that folder. have to compare the values in the array with the name of the images in the folder. when the match found that images has to be written in another folder. pls any give me some idea to do this. please help me..

Why calculate max(x) twice? Wouldn’t “[v1,ind1] = max(v)” be more efficient?

[v,ind]=max(max(X(:)));

[y,x] = ind2sub(size(X),ind);

do the same 🙂

You mean:

[v,ind]=max(X(:));

[y,x] = ind2sub(size(X),ind);

right?

Thanks for the tip 🙂
