Match n Freq - Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency.
Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Minimizing Intersymbol Interference in a read/write channel for disc drives by shaping and slimming an isolated readback pulse was the main objective for writing this program.

Industry problems with solutions over the past twenty plus years have been put into a textbook to show the power of Calculus-level Problem-Solving. The software architect behind Calculus Compilers was Joe Thames.
