Functions
double	itpp::mean (const vec &v)
	The mean value.
std::complex< double >	itpp::mean (const cvec &v)
	The mean value.
double	itpp::mean (const svec &v)
	The mean value.

	Calculate the Frobenius norm of a matrix for s = "fro".
double	itpp::variance (const cvec &v)
	The variance of the elements in the vector. Normalized with N-1 to be unbiased.
double	itpp::moment (const vec &x, const int r)
	Calculate the central moment of vector x.
double	itpp::skewness (const vec &x)
	Calculate the skewness excess of the input vector x.
