void XMFLOAT4X3()

Default constructor for XMFLOAT4X3

Default constructor for XMFLOAT4X3

void XMFLOAT4X3( const XMFLOAT4X3 & unnamedParam1)

Default constructor for XMFLOAT4X3

Default constructor for XMFLOAT4X3

XMFLOAT4X3 & operator=( const XMFLOAT4X3 & unnamedParam1)

Assigns the vector component data from one instance of XMFLOAT4X3 to the current instance of XMFLOAT4X3.

This operator assigns the vector component data from one instance of XMFLOAT4X3 to the current instance of XMFLOAT4X3.

void XMFLOAT4X3( XMFLOAT4X3 && unnamedParam1)

Default constructor for XMFLOAT4X3

Default constructor for XMFLOAT4X3

XMFLOAT4X3 & operator=( XMFLOAT4X3 && unnamedParam1)

void XMFLOAT4X3( float m00, float m01, float m02, float m10, float m11, float m12, float m20, float m21, float m22, float m30, float m31, float m32) noexcept

Initializes a new instance of the XMFLOAT4X3 structure from twelve scalar float values.

Initializes a new instance of the XMFLOAT4X3 structure from twelve scalar float values.

void XMFLOAT4X3( const float *pArray) noexcept

Initializes a new instance of the XMFLOAT4X3 structure from a twelve element float array.

Initializes a new instance of the XMFLOAT4X3 structure from a twelve element float array.

float operator()( size_t Row, size_t Column) noexcept

float & operator()( size_t Row, size_t Column) noexcept

Returns a reference to a matrix element of an instance XMFLOAT4X3 as specified by row and column arguments.

This operator returns a reference to a matrix element of an instance XMFLOAT4X3 as specified by row and column arguments.

bool operator==( const XMFLOAT4X3 & unnamedParam1)

auto operator<=>( const XMFLOAT4X3 & unnamedParam1)

Remarks

Scalar members of XMFLOAT4X3 are of the form _RowCol, and provide one based indexing, where Row specifies the one's based matrix row (running from 1 to 4), and Col specifies the one's based matrix column (running from 1 to 3).

The two dimensional 4*3 array member of XMFLOAT4X3, m, provides zero based indexing of the structure's matrix. When accessing XMFLOAT4X3m[Row,Col], Row can run from 0 to 3 and Col can run from 0 to 2.

XMFLOAT4X3 can be loaded into instances of XMVECTOR by using XMLoadFloat4x3.

Instances of XMVECTOR can be stored into an instance of XMFLOAT4X3 with XMStoreFloat4x3.
