Hi. I am trying to use 'ezcontour'. I want to know how to increase number of lines that appear in these contour plots. Thanks.

help contour?

... contour(Z, N) and contour(X, Y, Z, N) draw N contour lines, ...

... contour(Z, V) and contour(X, Y, Z, V) draw LENGTH(V) contour lines at the values specified in vector V. ...

Did I miss your point?

THe 'N' parameter does not apply to ezcontour, only contour.

Use the Level Step parameter, e.g.:

>> h=ezcontour(@(x,y)pdf(obj,[x y]),[-3 5],[-4 5],100);

>> h.LevelStep=0.01;

It is also convenient to use a custom list, such as:

>> h.LevelList=[0.001 linspace(0,0.12,20)];
