Then the following 2 entries from the 3.0.1 NEWS file are probably of 
interest to you.

 ** For compatibility with Matlab, normcdf, norminv, normpdf, and
    normrnd have been modified to compute distributions using the
    standard deviation instead of the variance.


 ** For compatibility with Matlab, gamcdf, gaminv, gampdf, gamrnd,
    expcdf, expinv, exppdf and exprnd have been modified to compute
    the distributions using the standard scale factor rather than
    one over the scale factor.
