%description
A collection of functions to support matrix calculations for probability,
econometric and numerical analysis. There are additional functions that
are comparable to APL functions which are useful for actuarial models such
as pension mathematics. This package is used for teaching and research
purposes at the Department of Finance and Risk Engineering, New York
University, Polytechnic Institute, Brooklyn, NY 11201. Horn, R.A. (1990)
