How to rotate contours generated using contourf command in MATLAB R2014b?

rotating using get(gca, 'Children') doesn't seem to work.

do you mean actually rotating the data or something like 'rotate3d on'?

Sean's right. The rotate command only works on a few types of objects, and you probably want to try hgtransform instead.

That would look something like this:

g = hgtransform
contourf(peaks,'Parent',g)
set(g,'Matrix',makehgtform('zrotate',pi/3))

What do you mean by rotate?

>>rotate3d on

Still works.

In R2014b, contour is no longer a collection of patches but rather a contour plot object. If you look at it's properties, you might find what you want:

[c,h] = contourf(Z,10);
>> h
h = 
Contour with properties:
    LineColor: [0 0 0]
    LineStyle: '-'
    LineWidth: 0.5000

Does this imply that the rotation of the contours had to be done numerically? I don't want to do it interactively such as using the

rotate3d on

since there are other plotted overlaid in the same figure.

I'm not clear on what you mean by rotating. Whether it's interactive or programmatic, the whole figure will rotate. If you mean rotate the individual color patches relative to the rest of the figure, then you might want to look into using hgtransform.
