Trait MMul

pub trait MMul<Rhs>: Matrix
where
    Self::Output: Matrix,
{
    type Output;

    // Required method
    fn mul(self, rhs: Rhs) -> Self::Output;
}

Required Associated Types

type Output

Required Methods

fn mul(self, rhs: Rhs) -> Self::Output

Returns the matrix product

AB

Arguments

• rhs - A scalar or a matrix with height equal this matrix’s length

Examples

// Scaling
let a = [
    [1.0, 2.0],
    [3.0, 4.0]
];
let b = 2.0;
let ab = [
    [2.0, 4.0],
    [6.0, 8.0]
];
assert_eq!(a.mul(b), ab)
 
// Matrix multiplication
let a = [
    [1.0],
    [2.0],
    [3.0]
];
let b = [
    [1.0, 2.0, 3.0]
];
let ab = [
    [1.0, 2.0, 3.0],
    [2.0, 4.0, 6.0],
    [3.0, 6.0, 9.0]
];
assert_eq!(a.mul(b), ab)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
