I am trying to calculate norm two of a matrix. I know about the command mat_norm but it calculates only norm 1, infinity and frobenious. Is there a way to calculate norm trwo with one command or we need to make a program? Thanks in advance!!!Protopapas EleftheriosSat, 19 May 2018 14:17:44 -0000https://sourceforge.net/p/wxmaxima/discussion/435775/thread/6b05711d/?limit=25#d70aJim Bowery modified a comment on discussion Open Discussionhttps://sourceforge.net/p/wxmaxima/discussion/435775/thread/d0a13060/?limit=25#6867I want to create a video instructing prospective Windows 7 users of wxMaxima to download a library from github (specifically, the clifford algebra library), install it and run the demos.

I would gladly fix this myself, if I knew how. I use wxMaxima professionally, in an academic setting. The fact that I haven't been able to use draw has been a real problem.

Everything works fine except that some of the symbols in the Symbol Palette fail to appear and are replaced by the "missing character" box. See the attached image in the following post. Please note that the palette works, it's just that I can't see what the symbol is before choosing it. Has anybody else encountered this?
