Functions
template<typename T1 >
static void	op_var::apply (Mat< typename T1::pod_type > &out, const mtOp< typename T1::pod_type, T1, op_var > &in)
	For each row or for each column, find the variance. The result is stored in a dense matrix that has either one column or one row. The dimension, for which the variances are found, is set via the var() function.
template<typename eT >
static eT	op_var::direct_var (const eT *const X, const uword N, const uword norm_type=0)
	find the variance of an array
template<typename T >
static T	op_var::direct_var (const std::complex< T > *const X, const uword N, const uword norm_type=0)
	find the variance of an array (version for complex numbers)

void op_var::apply	(	Mat< typename T1::pod_type > &	out,
		const mtOp< typename T1::pod_type, T1, op_var > &	in
	)		[inline, static]

For each row or for each column, find the variance. The result is stored in a dense matrix that has either one column or one row. The dimension, for which the variances are found, is set via the var() function.
