Description

Hi @dlwh,

is it possible to draw contour plots like in octave, e.g. contour(u, v, z, [0, 0], 'LineWidth', 2)? I wanted to draw a polynomial decision boundary for logistic regression with scala/breeze like this: bildschirmfoto 2015-02-15 um 22 36 54

The scatter plot for the data works fine, but I cant find a way to plot such a decision boundary.

Many thanks in advance!
