Assigning Null / Multi-Dimensional Matrix

Hello,
I have a matrix with the dimensions of 4x2500 and I am generating this matrix in for loop. I want this matrix to be 4x1250. Without multi dimension I just write A(1:length(X)) = [] but I am stuck in multi dimension. This logic does not work in my operation.
when I say
A = [1:1:2500];
A (1:1250) = [];
it works and that is what i want to do.
but in multi dimension,
for i = 1:1:4
A(i,:) = ????????
end
Can someone help me? Thanks.

vectorized solution is the most efficient and simple. But, still if you need for loop, try this
x=1:5;
A = repmat(x,4,1);
for i = 3:-1:1 % if you want to delete from Column 3 then index i will be started from 3.
A(:,i) = []
end
