Scales the columns of the matrix by the values specified by a vector.

Definition

Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.2

protected virtual Matrix<T> ScaleColumnsCore(
	Vector<T> factors,
	Matrix<T>? result
)

Visual Basic

Protected Overridable Function ScaleColumnsCore ( 
	factors As Vector(Of T),
	result As Matrix(Of T)
) As Matrix(Of T)

C++/CLI

protected:
virtual Matrix<T>^ ScaleColumnsCore(
	Vector<T>^ factors, 
	Matrix<T>^ result
)

abstract ScaleColumnsCore : 
        factors : Vector<'T> * 
        result : Matrix<'T> -> Matrix<'T> 
override ScaleColumnsCore : 
        factors : Vector<'T> * 
        result : Matrix<'T> -> Matrix<'T>

Parameters

factors Vector<T>: A vector containing the scale factors.
result Matrix<T>: The matrix that is to hold the result. May be null.

Return Value

Matrix<T>
A reference to this instance.

Remarks

This method is equivalent to pre-multiplying the matrix with a diagonal matrix with factors as the main diagonal.

Exceptions

ArgumentNullException	factors is .
DimensionMismatchException	The length of factors does not equal the number of columns of the matrix.
