Trait truck_rendimpl::modeling::Matrix

pub trait Matrix: VectorSpace + Index<usize, Output = Self::Column, Output = Self::Column> + IndexMut<usize> where
    Self::Scalar: Float, {
    type Row: Array + VectorSpace;
    type Column: Array + VectorSpace;
    type Transpose: Matrix;
    pub fn row(&self, r: usize) -> Self::Row;
    pub fn swap_rows(&mut self, a: usize, b: usize);
    pub fn swap_columns(&mut self, a: usize, b: usize);
    pub fn swap_elements(&mut self, a: (usize, usize), b: (usize, usize));
    pub fn transpose(&self) -> Self::Transpose;

    pub fn as_ptr(&self) -> *const Self::Scalar { ... }
    pub fn as_mut_ptr(&mut self) -> *mut Self::Scalar { ... }
    pub fn replace_col(&mut self, c: usize, src: Self::Column) -> Self::Column { ... }
}

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.
