TMtx.Determinant Method (TMtxType)

Determinant of squared matrix.

Pascal

function Determinant(MtxType: TMtxType = mtGeneral): double; overload;

Calculate the determinant of squared real matrix. An exception is raised if the calling matrix TMtxVec.ComplexComplexproperty is true.

Example

var A: TMtx; b: double; begin CreateIt(A); try A.SetIt(2,2,false,[1,2, 2,4]); // 2x2, not complex matrix b := A.Determinant; // 4 + 4 = 9 finally FreeIt(A); end; end;
