MATLAB: How to find the indices of the 3 largest values in the matrix

indexlinear indexingmatrixmax

I have a matrix with varying values. I want to find the 3 largest values in this matrix and assign their indices to 3 different variables. How can I do this as simply as possible? Example matrix:
   99 45 93 64
   12 83 24 85
   39 71 29 13
After finding the largest values – 99,93,85. I'd like to find their respective indices (with linear indexing). So that would be 1,7,11.
   a = 1;
   b = 7;
   c = 11;

Best Answer

A = [99 45 93 64;
   12 83 24 85
   39 71 29 13];
[ii,ii] = sort(A(:),'descend');
out = ii(1:3);
