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.

void op_var::apply	(	Mat< typename T1::pod_type > &	out,

	)			[inline, static, inherited]

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.
