To find the maximum value in each column of a cell array.

I am having cell array of 3072*2 cell, each containing matrix values of 5*1295 double. I need to find the maximum value of each 1295 column. How can I do that? Please help me with this. Thanks in advance.

Let A be your cell array of size 3072*2 where each cell has a matrix of size 5x1295.

[m,n] = size(A) ;
iwant = cell(m,n) ;
for i = 1:m
    for j = 1:n
        iwant{i,j}=max(A{i,j}) ;
    end
end

If, I want to store the maximum value ID only (in the same scenario) means i.e. column id or column number (among 5 column), How can I change above function? Kindly help me with this too. Thanks in advance.

hi,

I hope this will help,

C = {[1 2;10 11]  [2 3;4 5]; [3 4;9 10] [4 5;2 3];[2 3;2 3] [5 6;3 4]}

C = 3×2 cell array
    {2×2 double}    {2×2 double}
    {2×2 double}    {2×2 double}
    {2×2 double}    {2×2 double}

[r,c]=size(C);
for i=1:r
    for j=1:c
        max(C{i,j})
    end
end    

ans = 1×2

10 11

ans = 1×2

4 5

ans = 1×2

9 10

ans = 1×2

4 5

ans = 1×2

2 3

ans = 1×2

5 6
