Functions

Name	Description
Equal(MatrixParam, MatrixParam)	Return true if all corresponding matrix elements are exactly equal.
EqualWithinEpsilon(MatrixParam, MatrixParam)	Return true if all corresponding matrix elements are within an epsilon.
GetMatrixFromString(const C *)	Read 16 float values from a string and build a Matrix. Same argument order as the 16 float constructor.
IsFinite(MatrixParam)	Returns true if all of the 16 elements of m are finite.
IsNan(MatrixParam)	Returns true if all of the 16 elements of m are finite.
IsPermutationMatrix(MatrixParam)	Returns true if the matrix is a valid permutation matrix, where each column and each row consists of a single positive or negative "1" and the rest "0".
MatrixToString(MatrixParam)	Creates a GeoString containing the 16 elements of the matrix (space-separated) in a form compatible with GetMatrixFromString.
MatrixToUtf8String(MatrixParam)	Creates a GeoString containing the 16 elements of the matrix (space-separated) in a form compatible with GetMatrixFromString.
MDet(MatrixParam)	Determinant (returned as a broadcast float)
MGetRotation(Geo::MatrixParam)	Deconstruct the matrix to retrieve the rotation part as a quaternion.
MGetTranslation(Geo::MatrixParam)	Deconstruct the matrix to retrieve the translation part as a vector.
MInverse(MatrixParam)	Generalised inverse.
MInverse(MatrixParam, v128)	with a precomputed 1/determinant
MInverseSimple(MatrixParam)	Inverts assuming only rotation and translation.
MTranspose(MatrixParam)	Determinant (returned as a broadcast float)
