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) |
