MATLAB: Creating matrix of maximum values (evaluating along time dimension) for each cell from multiple dimension matrix

matrixmaxmultidimensional

Given a matrix A ([long,lat,time], I need to create an array B [long,lat] where each cell in B is the maximum value from the corresponding cell that maximized the dimension time in A.

Doc max. It has option to find the maximum value along a prescribed dimension; max(A,[],dim). If your matrix is 3D max(A,[],3) shall work.

You want to transpose the matrix?

New_Matrix = Old_Matrix';

MATLAB: Get the max value and the indices of max value across a series of matrices

Let A - your cell array (25 x 50) with double matrix 128 x 128.

n = size(A,1);
maxvalue = cell(n,1);
maxidx = cell(n,1);
for ii = 1:n
    [maxvalue{ii},maxidx{ii}] = max(cat(3,A{ii,:}),[],3);
end
