    mean: &mut impl ToOutputArray,
    variance: &mut impl ToOutputArray
) -> Result<()>
Expand description

Computes the mean and variance of a given matrix along its rows.

§Parameters

  • A: Input NxN matrix.
  • mean: Output Nx1 matrix with computed mean.
  • variance: Output Nx1 matrix with computed variance.

It computes in the same way as woud do [reduce] but with \a Variance function.
