For example, with floats, using Gaussian elimination, the determinant of a matrix containing polynomials might be returned as a rational function ("quolynomial") due to round-off errors. This is most useful in the new float versions. $, which means greatest integer in Fermat, will now similarly truncate a quolynomial. It could fail if the degrees were large enough. There was a bug in a speedup technique for multiplying large two variable polynomials. It would manifest unpredictably, but inevitably Pseudet would finish too soon with the wrong answer. There was a bug in Pseudet when the matrix was not of maximal rank and pivot strategy 5 was chosen. Also, refined heuristics for multivariable polynomial gcd. There was a bug in a speedup technique involving multiplying large two variable polynomials.
(You don't have to have a PayPal account.) Institutions or those with grant money should contribute $US 60 per machine. Researchers with demanding problems would probably be better using Linux or Mac.įermat is freeware. Windows does not seem to manage RAM (heap, stack) quite so well as Linux or Mac. The only difference I have seen is that some matrix normalization routines (determinant, Pseudet) run more slowly than on Linux unless the pivot strategy &u = 5 is selected. Since it is new, it should be considered a beta version. A user reported that it works on Windows 7.
#CYGWIN FOR MAC OS X DOWNLOAD MANUAL#
Since it is exactly the same as the Linux and Mac version, the manual is the same. This version runs on every Windows system that I have tried, including Windows 7. Unless you already have it, leave it in the Fermat folder. That file is freely available on the Cygwin website too. The download includes the important file cygwin1.dll. Thank you Cygwin!ĭownload this Windows version of Fermat, 3.9.9x, here. That old version is distinctly inferior in many ways. For the old, now obsolete, Windows version see. It uses exactly the same C code as the Linux and Mac versions. This is the new (as of November 2011) version of Fermat for Windows.
