Operate on all the columns of a matrix

I have a 100*3 matrix and want to normalize each column. Sth like this:

for i=1:3
    norm=normalize(mat(:,i))
end

Is there any shorter way to remove "for loop"? This matrix is part of a code that changes its columns in each simulation.

"N = normalize(A,dim) returns the z-score along dimension dim. For example, normalize(A,2) normalizes each row."

norm_mat=normalize(mat,1);

norm is a function, so I don't recommend using it as a variable name
