Hi, Dear all

I program the following procedure:

function [row_index,col_index,maxA]= max_array(A)
[row,col]=size(A);
[AM,IM]=max(A);
if row==1
row_index=row;
col_index=IM;
maxA=AM;
else
[AMx,J]=max(AM);
row_index=IM(J);
col_index=J;
maxA=AMx;
end
end

why only outputs the row_index, but not the col_index and maxA?

Thank you all
Tom

Probably because when you called this function, you called it like:

outputs = max_array(y);

You only asked for one output, so the function only returned one output. If
you want all three:

[rowInd, colInd, maxValue] = max_array(y)

How do you call the function?
if you want all 3 oupts returned, you need something like:

[a,b,c]= max_array(A)
