TMtx::Determinant Method

TMtx Class

Overload List

#SignatureDescription
1double Determinant(TMtxType MtxType = TMtxType::mtGeneral);Determinant of squared matrix.
2void Determinant(TCplx &result, TMtxType MtxType = TMtxType::mtGeneral);Calculates the determinant of squared complex matrix.

Overload 1: double Determinant(TMtxType MtxType = TMtxType::mtGeneral);

Determinant of squared matrix.

#NameTypeDescription
1MtxType = TMtxType::mtGeneralTMtxType
Remarks:

Calculate the determinant of squared real matrix. An exception is raised if the calling matrix TMtx::Complex property is true.

Examples
#include "MtxVec.h"
#include "Units.MtxVec.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxVec;

void Example()
{
    TMtx* A;
    double b;

    CreateIt(A);
    A->SetIt(2, 2, false, DewArray<double>{1, 2, 2, 4}); // 2x2, not complex matrix
    b = A->Determinant(); // 4 + 4 = 9
    FreeIt(A);
}
