:param ctype: type of the matrixl; it equals 'CV_64F' by default.
- :param cov_mat: output covariance matrix (specific to C syntax).
-
:param mean: input or output (depending on the flags) array as the average value of the input vectors.
:param vects: a set of vectors.
* **CMP_LE** ``src1`` is less than or equal to ``src2``.
* **CMP_NE** ``src1`` is unequal to ``src2``.
- :param cmp_op: a flag, that specifies correspondence between the arrays (specific to C syntax; for possible values see 'cmpop above).
