Calculates matrix inverse (Mtx^-1).

Pascal
function Inv: TMtx; overload;
Description

Calculate the inverse (Mtx^-1) of the calling matrix. If the calling matrix is not Quadratic, an exception is raised. Parameter TMtxType determines which optimized method will be used for calculating the inverse matrix. If MtxType is omitted, the default value mtGeneral (general quadratic matrix) is used.

Notes

The MtxType parameter is not verified. To determine if the calling matrix type is actually MtxType, use the DetectMtxType method.
