irotate

Rotate image

out = irotate(im, angle, options) is a version of the image im that has been rotated about its centre.

Options

'outsize', S	set size of output image to HxW where S=[W,H]
'crop'	return central part of image, same size as IM
'scale', S	scale the image size by S (default 1)
'extrapval', V	set background pixels to V (default 0)
'smooth', S	initially smooth the image with a Gaussian of standard deviation S

Rotation is defined with respect to a z-axis which is into the image.
Counter-clockwise is a positive angle.
The pixels in the corners of the resulting image will be undefined and set to the 'extrapval'.
