About two years ago the following code was working without error: F(q,r):=3*r^2 + 5*q;
wxplot2d(F(1,r),[r,0,5],[legend,"F"],[xlabel,"r[bohr]"], [ylabel,"denso"]); Now with Maxima version 5.47.0 and wxmaxima 23.12.0 installed with MacPorts on an iMac there is the following error: Maxima encountered a Lisp error The value "F" is not of type LIST ...... However if I change the wxplot2d command with wxplot2d(F(1,r),[r,0,5],[legend,"F",""],[xlabel,"r[bohr]"], [ylabel,"denso"]); then it works again without errors. Are there any reason? Before to change all the old programs, are there any possibility to recover this problem? Thank you very much. Alby Stalks
