Hi, I am having problems in a loop with the function "findpeaks.m". I think the solution is very simple, but I cannot find it.
My code is:
A=[1 2 3 1 2; 1 15 2 5 2;1 2 1 2 1];
[x y]=size(A);
a=zeros(x,5);
for i=1:1:x;
a(i)=findpeaks(A(i,:));
end
The problem is findpeaks function give me vectors with different size. Could someone help me? Thanks in advance.

Hi Maria, Because you cannot expect the number of peaks in the rows of A to be the same in each row, you can use a cell array to capture the number of peaks in each row.
A=[1 2 3 1 2; 1 15 2 5 2;1 2 1 2 1];
[x y]=size(A);
for i=1:x
a{i}=findpeaks(A(i,:));
end
