ROT_SVD2X2 can be used when we are solving large matrix SVD problem,
which can be divided into many small matrices such as 2x2.
As a subroutine, it can be applied to solve the subproblems with speed.
It can compute SVD of 2x2 complex matrix at one step finding
two rotation matrices, while iteration-based approach may take several steps.
In real matrix, ROT_DSVD2X2 computes the real rotation matrices to obtain the singular value decomposition of a 2-by-2 real matrix.

1.1.0.0

Algorithm is modified by using column-uncorrelated matrix decomposition, as in <http://scicomp.stackexchange.com/questions/8899/robust-algorithm-for-2x2-svd,>
which only handles real matrix whereas the updated algorithm can do it with complex cases.
