Methods

appendColumns(dynamic newColumns) → Matrix

Available on Matrix, provided by the MatrixManipulationExtension extension

Appends new columns to the matrix with the values provided in newColumns.

appendRows(dynamic newRows) → Matrix

Available on Matrix, provided by the MatrixManipulationExtension extension

Appends new rows to the matrix with the values provided in newRows.

apply(dynamic func(dynamic)) → Matrix

Available on Matrix, provided by the MatrixManipulationExtension extension

Applies the given function func to each element in the matrix and returns a new matrix with the results.

applyToRows(List func(List)) → Matrix

Available on Matrix, provided by the MatrixManipulationExtension extension

Applies the given function func to each row in the matrix and returns a new matrix with the results.

augment(dynamic augmentee) → Matrix

copy() → Matrix

Available on Matrix, provided by the MatrixManipulationExtension extension

Returns a copy of the matrix.

copyFrom(Matrix other, {bool resize = false, bool retainSize = false}) → void

Available on Matrix, provided by the MatrixManipulationExtension extension

Copies the elements from another matrix into this matrix.

elementAt(int row, int col) → dynamic

Available on Matrix, provided by the MatrixManipulationExtension extension
