Matrix

mixin Matrix

Interface for matrix implementations. A matrix is a rectangular array of numbers.

cofactor	Compute the cofactor of the matrix.
determinant	Compute the determinant of the matrix.
fill	Set every element in the matrix to the given val.
get	Get the element at `A[i,j]`, where `i` is the row index, and `j` is column index.
inverse	Compute the inverse of the matrix.
isSquare	Return true if the matrix is square.
minus	Computes `A - B` and returns a new matrix.
mult	Computes `A * B` and returns a new matrix.
multScalar	Computes `x * A`.
numCols	The number of columns in the matrix.
numRows	The number of rows in the matrix.
plus	Computes `A + B` and returns a new matrix.
set	Set the element at `A[i,j]`, where `i` is the row index, and `j` is column index.
transpose	Get the transpose of the matrix.

abstract Matrix cofactor()

Compute the cofactor of the matrix. The matrix must be square.

abstract Float determinant()

Compute the determinant of the matrix. The matrix must be square.

abstract This fill(Float val)

Set every element in the matrix to the given val.

abstract Float get(Int i, Int j)

Get the element at A[i,j], where i is the row index, and j is column index.

abstract Matrix inverse()

Compute the inverse of the matrix.

abstract Bool isSquare()

Return true if the matrix is square.

@Operator abstract Matrix minus(Matrix b)

Computes A - B and returns a new matrix.

@Operator abstract Matrix mult(Matrix b)

Computes A * B and returns a new matrix.

abstract This multScalar(Float x)

Computes x * A.

abstract Int numCols()

The number of columns in the matrix.

abstract Int numRows()

The number of rows in the matrix.

@Operator abstract Matrix plus(Matrix b)

Computes A + B and returns a new matrix.

abstract This set(Int i, Int j, Float val)

Set the element at A[i,j], where i is the row index, and j is column index.

abstract Matrix transpose()

Get the transpose of the matrix.
