Matrix

Abstract Value Members

abstract def apply(i: Int, j: Int): Double

Gets the (i, j)-th element.
Gets the (i, j)-th element.

abstract def copy: Matrix

Get a deep copy of the matrix.
Get a deep copy of the matrix.

Annotations
@Since( "2.0.0" )
abstract def numActives: Int

Find the number of values stored explicitly.
Find the number of values stored explicitly. These values can be zero as well.

Annotations
@Since( "2.0.0" )
abstract def numCols: Int

Number of columns.
