Octave 3.0.3 and contourf

[Marco Caliari]

Dear maintainers,

if I try contourf(peaks) in Octave 3.0.3 I get

warning: meaning may have changed due to change in precedence for && and || operators
error: patch: X and Y must be of same size
error: evaluating if command near line 230, column 3
error: called from `contourf:parse_args' in file `/usr/local/share/octave/3.0.3/m/plot/contourf.m'
error: called from `contourf' in file `/usr/local/share/octave/3.0.3/m/plot/contourf.m'

I had to modify line 230 of contourf.m

   if (!isvector (X) || !isvector (Y) && any (size (X) != size (Y)))

to

   if ((!isvector (X) || !isvector (Y)) && any (size (X) != size (Y)))

in order to have contourf working again.

Best regards,

Marco
