Yes. For example, the time series section of the NAG Fortran 90 library http://www.nag.co.uk/numeric/FN/manual/html/c29_fn04.html does not have GARCH models, which the F77 library http://www.nag.co.uk/numeric/fl/manual/html/G13/g13_conts.html does have. In general there are more algorithms in the F77 library. IMSL carried over the ENTIRE content of its Fortran 77 library to Fortran 90. So did Numerical Recipes. ____________________________________________________________________________________ Looking for earth-friendly autos? Browse Top Cars by "Green Rating" at Yahoo!
