(latex(a\v), a)

gives an error.

I think it has to do with the parsing of latex(a\v); it seems to try doing "(latex(a._backslash_(v), a)" (note the missing parenthesis in the call to latex.

You see this parsing in the error from:

def _(a=matrix(QQ,3,3,range(9)), v=matrix(QQ,3,1,range(3))):
    html('$$%s %s = %s$$'%(latex(a), latex(a\v), latex(v)))

with the patch from #3121

  • Milestone changed from sage-4.0.1 to sage-duplicate/invalid/wontfix
  • Resolution set to invalid
  • Status changed from new to closed

This now works (most likely with the change to how the backslash operator is implemented)

| Sage Version 4.0.1.rc1, Release Date: 2009-06-04                   |
