}Expand description
A column-major matrix of arbitrary dimensions.
Because this is constrained to the VectorSpace trait, this means that
following operators are required to be implemented:
Matrix addition:
Add<Output = Self>Sub<Output = Self>Neg<Output = Self>
Scalar multiplication:
Mul<Self::Scalar, Output = Self>Div<Self::Scalar, Output = Self>Rem<Self::Scalar, Output = Self>
Note that matrix multiplication is not required for implementors of this
trait. This is due to the complexities of implementing these operators with
Rust’s current type system. For the multiplication of square matrices,
see SquareMatrix.
Associated Types

The column vector of the matrix.

Provided methods
fn as_mut_ptr(&mut self) -> *mut Self::Scalar
fn as_mut_ptr(&mut self) -> *mut Self::Scalar
Get a mutable pointer to the first element of the array.
