Overload List

#	Signature	Description
1	int Find(const double x);	Finds a match for X in object values.
2	int Find(const TCplx &x);	Compare complex value X with all calling object elements.

Overload 1: int Find(const double x);

Finds a match for X in object values.

#	Name	Type	Description
1	x	const double

Returns: the index of first matched element. If no matching elements are found, the result is -1.

Examples

#include "Units.MtxVec.h"

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

void Example()
{
    TVec* a;
    CreateIt(a);
    a->SetIt(false, DewArray<double>{2,5,1,6});
    int indes = a->Find(1.0);  // returns 2 (the arrays are zero based)
    FreeIt(a);
}
