How to get the new matrix after rotation

If I am rotating a matrix by using:

[C,h] = contour(x,y,Conv_Norm);
rotate(get(h,'children'),[0 0 1],angle)

Is there a way I get the new rotated matrix values?

Answer 1

[Adam]

get( h, 'XData' )
get( h, 'YData' )

should give the rotated data values

Thank you for your reply. But I am looking for the matrix Conv_Norm values after rotation not the axis data. Will that matrix remain unchanged after rotation?

Actually I am rotating the matrix Conv_Norm by a certain angle and then I require the rotated matrix.

I tried using imrotate which doesn't give the desired results
