Floating Point Exception

Functions accompanying MATLAB News & Notes article "Fixed-point Signal Processing: Getting Started" by Darel A. Linebarger and Thomas A. Bryan, 2004. The functions include an FIR filter in M that can be run in fixed-point and floating-point.

This simulation illustrates the effects of the fixed-pointcomputations on the closed-loop precision for a 16-bits PID controller.The rounding mode, the point where the truncations take place and theformat width for the internal variable have a significant action on theclosed-loop permanent...

Genefer is a program for finding large Generalised Fermat Primes (b^2^n+1), originally written by Yves Gallot in 2001. It has since been updated by David Underbakke and Mark Rodenkirch to provide checkpointing and other features. In addition, David and Mark developed two new versions of Genefer -...
