float3x2 structure

A 3x2 matrix, used for 2D transforms.

This matrix type uses a row vector layout. The x and y of this matrix's translation vector correspond to the fields m31, m32.

This type is available only in C++. Its .NET equivalent is System.Numerics.Matrix3x2.

Constructors

Operators

Name Description
float3x2 operator+ (float3x2 const& value1, float3x2 const& value2) Adds each component of a matrix to another matrix.
float3x2 operator- (float3x2 const& value1, float3x2 const& value2) Subtracts each component of a matrix from another matrix.
float3x2 operator* (float3x2 const& value1, float3x2 const& value2) Multiplies a matrix by another matrix. This has the effect of concatenating two transforms.
float3x2 operator* (float3x2 const& value1, float value2) Multiplies each component of a matrix by a scalar value.
float3x2 operator- (float3x2 const& value) Negates each component of a matrix.
float3x2& operator+= (float3x2& value1, float3x2 const& value2) In-place adds each component of a matrix to another matrix.
float3x2& operator-= (float3x2& value1, float3x2 const& value2) In-place subtracts each component of a matrix from another matrix.
float3x2& operator*= (float3x2& value1, float3x2 const& value2) In-place multiplies a matrix by another matrix. This has the effect of concatenating two transforms.
float3x2& operator*= (float3x2& value1, float value2) In-place multiplies each component of a matrix by a scalar value.

bool operator!= (float3x2 const& value1, float3x2 const& value2) Determines whether two instances of float3x2 are not equal.
operator Microsoft::?Graphics::?Canvas::?Numerics::?Matrix3x2() const Converts a float3x2 to a Microsoft.Graphics.Canvas.Numerics.Matrix3x2.
