MATLAB: Finding Max Value From Matlab Variable

max value and its corresponding value

Hi Experts,

I have a variable

out

i want to extract the max value and its corresponding cell value i.e 17531 and 3 …..i used max function i.e

a = max(out); 
but it is displaying 4 17531.............I dont know why it is showing 4 instead of 3???Please help

That is a nice one! But in the doc it says

"If A is a matrix, then max(A) treats the columns of A as vectors and returns a row vector of largest elements."

So you maybe want to do something else? Like

[a,ix]=max(out(:,2))

Use max, and some indexing if needed:

A = [...]; % some matrix
N = 3; % the row that you want
max(A(N,:))

Not sure what you mean by empty, but if you mean all zeros, try this:

cp = zeros(mx_row, mx_col);

If you don't want zeros and truly want empty, then it's a contradiction if you want to use numerical arrays - you'd have to use a cell array like Azzi showed. But cell array's are complicated, especially for beginners, so if you want to use them, see the FAQ
