exp function on vector

MY problem is that exp() does not seem to function properly when used on a vector.
The relevant code is:
t=sum(X1.*repmat(BETA',n,1),2) + GAMMA(l); e.g. % 400x1 vector
p_ik = exp(t);
However, for example p_ik(400) is totally different from exp(t(400)), which mathematically should be equal. The difference is in the range 100's, exp(t(400)) = 909, p_ik(400) = 0.0910. Any ideas what the problem is/ how to solve it?
Any help why exp() is not functioning correctly on the matrix
