IMSL by Perforce Testimonials

"The IMSL Library is a great transition tool and helped me quickly move my projects and applications to Fortran; and that was without me having experience with Fortran at the time. It was much faster for me to use procedures from the IMSL Fortran Library than create those same procedures on my own."

"Using rigorously tested algorithms from IMSL is clearly better than developing our own. Developer’s time is extremely expensive in comparison to the cost of the libraries."
