Function expm::expm

pub fn expm<S1, S2>(a: &ArrayBase<S1, Ix2>, b: &mut ArrayBase<S2, Ix2>) where
    S1: Data<Elem = f64>,
    S2: DataMut<Elem = f64>, 

Calculate the matrix exponential of the n×n matrix a storing the result in matrix b.

NOTE: Panics if input matrices a and b don't have matching dimensions, are not square, not in row-major order, or don't have the same dimension as the Expm object expm is called on.
