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)];
also refer to http://uk.mathworks.com/help/matlab/ref/contour-properties.html#zmw57dd0e125000 for more options
