Function flatten_owned 

pub fn flatten_owned<T>(matrix: AbstractLiteral<T>) -> impl Iterator<Item = T>
where
    T: MatrixValue,

Consumes a multi-dimensional matrix and returns a one-dimensional slice of its elements. The elements are returned in row-major ordering (see enumerate_indices).

Panics

• If the number or type of elements in each dimension is inconsistent.
• If matrix is not a matrix.
