When it is possible with mathematics
It should be possible in C++ (but not everything is easy ;-) )
But when you post a question with no details, it is nearly impossible to answer it!
Do you have an N-dimensional array you want to rotate?
Do you have an array with 2-dimensional coordinates which you want to rotate?
Do you have an array representing a square (left,right,top,bottom) you want to rotate?
im doing fingerprint recognition for different orientations. In the system, i need to rotate the images of 200*200 dimension and match the images. So it's a 200*200 array. But i have no idea which (x,y) coordinate will be the rotational point.
which part of maths can i apply? will matrix help? how?
But when you want to do recognition of fingerprints, isn't it better to extract some features from one image (some vectors, distance between lines, number of lines, corners, curves, ...) and compare these between the images (with rotation of the features).
