Error: var.m

[Michael D. Godfrey]

A recent update to var.m has gone wrong:

octave:15> var(DTO)
error: `a' undefined near line 59 column 13
error: evaluating argument list element number 1
error: evaluating argument list element number 1
error: called from:
error:   /usr/local/share/octave/3.1.54+/m/statistics/base/var.m at line 
59, column 5

Replacement with var.m from 3.1.51+ solves the problem for the time being.
The changeset which caused the problem seems to be:
