When I was a high-school student I learned how to write computer programs. During the last four decades I used several programming languages for work, fun, and research. In fact during these years, I wrote programs in EDL (IBM series/1 event driven language), Fortran IV, Fortran 77, MS-DOS Basic, Cobol, Digital PDP-11 Assembler, Pascal, Modula-2, LISP, C. More recently I learned how to use some scripting languages as python and the ones of Pari/GP and MAXIMA. In several occasions I had the chance to exploit my programming skills for some mathematical purpose; sometimes I got some publishable results. In this page I collect some links to webpages containing softwares and numerical results.
Due to the phenomenon mentioned in P0 below, I have to state the obvious fact that if you wish to use some of the softwares below for your own research, you should acknowledge the author and cite the relevant paper in which the program was used first. In other words, you can use them but you have to cite the paper of mine that contains such programs. I was already forced to remove some of the source codes from these pages!!!
[P0] Sometimes I helped colleagues by providing the numerical result they needed or some of the following programs, see, e.g., these papers [C1] , [C2] , [C3] , [C4] .
Sometimes they directly used my programs without citing my papers (I don't know why !!!): [U1] , [U2] , [U3] .
