Hello all,
I don't have a Image processing toolbox to use imrotate function, So please let me know any other method or procedure to do this.
I need the pass the angle of rotation from 0 to 360 degree then the image should rotate with corresponding angle.
Best Regards,
Raghavendra

If you don't have IPT, MIMT imrotateFB() will work, and the syntax is similar. It will run faster with IPT available, but will still run without it. It should also still run in R2012x. Check the documentation, but most of the options are supported in fallback mode.
inpict = imread('peppers.png');
outpict = imrotateFB(inpict,30,'bilinear','crop');
imshow(outpict)
