[Octave-bug-tracker] [bug #31305] slow contour plot

[Gilberto A S Segundo]

Follow-up Comment #39, bug #31305 (project octave):

Hello. I'm using Debian Linux, 32 bits.
I used octave 3.2.4 from Debian repository and octave 3.4.1 compiled by
myself. In both the contour function is very slow compared with matlab 2010b
(7.11.0) for linux.

Running the commands:

tic;
contour(rand(20))
toc;

I got:
- octave 3.2.4: Elapsed time is 7.66252 seconds
- octave 3.4.1: Elapsed time is 25.7015 seconds
- matlab 2010b: Elapsed time is 0.963400 seconds
