Public Member Functions

 Matrix3 () noexcept
 Construct an identity matrix.
 
 Matrix3 (const Matrix3 &matrix) noexcept=default
 Copy-construct from another matrix.
 
 Matrix3 (float v00, float v01, float v02, float v10, float v11, float v12, float v20, float v21, float v22) noexcept
 Construct from values.
 
 Matrix3 (const float *data) noexcept
 Construct from a float array.
 
Matrix3operator= (const Matrix3 &rhs) noexcept=default
 Assign from another matrix.
 
bool operator== (const Matrix3 &rhs) const
 Test for equality with another matrix without epsilon.
 
bool operator!= (const Matrix3 &rhs) const
 Test for inequality with another matrix without epsilon.
 
Vector3 operator* (const Vector3 &rhs) const
 Multiply a Vector3.
 
Matrix3 operator+ (const Matrix3 &rhs) const

float Element (unsigned i, unsigned j) const
 Return matrix element.
 
Vector3 Row (unsigned i) const
 Return matrix row.
 
Vector3 Column (unsigned j) const
 Return matrix column.
 
bool IsNaN () const
 Return whether any element is NaN.
 
bool IsInf () const
