mixin Matrix

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

methods inverse

Compute the inverse of the matrix

minus

Computes A - B and returns a new matrix

mult

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

numRows

The number of rows in the matrix

cofactor

Compute the cofactor of the matrix

fill

Set every element in the matrix to the given val

numCols

The number of columns in the matrix

plus

Computes A + B and returns a new matrix

get

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

transpose

Get the transpose of the matrix

multScalar

Computes x * A

isSquare

Return true if the matrix is square

determinant

Compute the determinant of the matrix

cofactor abstract Matrix cofactor()

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

determinant abstract Float determinant()

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

fill abstract This fill(Float val)

Set every element in the matrix to the given val.

get 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.

inverse abstract Matrix inverse()

Compute the inverse of the matrix.

isSquare abstract Bool isSquare()

Return true if the matrix is square.

minus @Operator
abstract Matrix minus(Matrix b)

Computes A - B and returns a new matrix.

mult @Operator
abstract Matrix mult(Matrix b)

Computes A * B and returns a new matrix.

multScalar abstract This multScalar(Float x)

Computes x * A.

numCols abstract Int numCols()

The number of columns in the matrix.

numRows abstract Int numRows()

The number of rows in the matrix.

plus @Operator
abstract Matrix plus(Matrix b)

Computes A + B and returns a new matrix.

set 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.

transpose abstract Matrix transpose()

Get the transpose of the matrix.
