Hello,
I have a matrix A of size 24 x 365 with certain values and I have a matrix B of zeros of the same size as A. I would like to replace the zeros in B with the value 5 in the position mentioned in A.
For example
I would like B to look like
I would appreciate any help thank you!

The sizes of A and B in your example are not the same.
m=max(A,[],'all');
B=zeros(m,size(A,2));
a=A+(0:m:m*(size(A,2)-1));
B(a)=5;
