Given the camera matrix, can I find the focal length of this camera ?
Depends on what form the camera matrix is in.
Typically it is a 3x3 matrix that contains the focal lengths along the diagonal - with different Fx and Fy axis focal lengths to measure the astigmatism of the lens (the third value Fz isn't used)
