## suppressing certain warnings

In the following loop...
for j=1:n
y(:,j) = [zeros(j-1,1); x(1:length(x)-j+1 )];
endfor
(so, if j==1, zeros.m returns a nul matrix, and the first column of y
simply becomes x)
I get the following warning every time the loop goes through its first
iteration...
warning: empty matrix found in matrix list
which is due to having a nul matrix as the first element in my matrix
list.
1) Is there a way to suppress this warning, or only have it displayed
once? 2) Is there a better way to do what I want that doesn't
necessarily involve writing a conditional statement to check when j==1?
It's just that this loop, and similar ones, are rather numerous
throughout all my different functions and scripts, and I don't want to
go back and fix them all.
Thanks,
EJR
