Description
In Array_and_Matrix branch:
%!error
%! z03 = sym (zeros (0, 3));
%! z04 = sym (zeros (0, 4));
%! [z03; z04]
This test passes. It is an error. But the error message is not shown:
octave:43> [z03; z04]
pydebug: vertcat: all inputs must have the same number of columns
error: sym/vertcat method failed
error: called from
pycall_sympy__ at line 179 column 7
vertcat at line 67 column 5
The thing shown in pydebug should be the error message---here just hacked to show up:
'ncols = [number_of_columns(x) for x in args]'
'if not all_equal(*ncols):'
' msg = "vertcat: all inputs must have the same number of columns"'
+ ' dbout(msg)'
' raise ShapeError(msg)'
'CCC = [as_list_of_list(x) for x in args]'
'CC = flatten(CCC, levels=1)'
