Maybe Chris mentioned this in his talk, but I was reminded this morning that the calculator in emacs knows how to do algebra! This came up on the octave mailing list where some guy mentioned (and included a transcript) of using it thus: here's an actual example from a problem I did yesterday. I have in line "3:" two linearly independent solutions of u''(x) = 0, then in line "2:" their Wronskian matrix, then in line "1:" its symbolic matrix inverse This seemed particular topical given Eric's talk tonight. (He did say "advanced" emacs.) I'll be the one in the audience asking him to solve some systems of linear equations with emacs. ;)  Jeff Jeff Abrahamson <http://www.purple.com/jeff/> +1 215/8372287 GPG fingerprint: 1A1A BA95 D082 A558 A276 63C6 16BF 8C4C 0D1D AE4B Attachment:
