TMtxVecIntHelper.FindIndexes Method

Overload List

#	Signature	Description
1	TMtxVecInt FindIndexes(TMtxVecInt aThis, TMtxVec a, String op, TCplx b)	Fills the calling vector with indexes, where the logical expression is true.
2	TMtxVecInt FindIndexes(TMtxVecInt aThis, TMtxVec a, String op, TMtxVec b)	The b parameter is of Dew.Math.TMtxVec type.
3	TMtxVecInt FindIndexes(TMtxVecInt aThis, TMtxVec a, String op, Double b)	The b parameter is of double type.

Overload 1: TMtxVecInt FindIndexes(TMtxVecInt aThis, TMtxVec a, String op, TCplx b)

Fills the calling vector with indexes, where the logical expression is true.

#	Name	Type	Description
1	aThis	TMtxVecInt	source TVecInt or TMtxInt
2	a	TMtxVec	source TVec or TMtx
3	op	String
4	b	TCplx	scalar

Result: stored in self (calling object), returns self for chaining

Remarks:

Fills the calling vector with indexes, where the Op comparison between a and b is True. Op string parameter can be '<', '>', '>=','<=','=' or '<>'. The calling vector will be sized to match a.Length. On return it will be subranged to reflect actual number of matching elements. The method will not raise an exception, if the calling vector (Self) is already subranged. Check the TVec.SetSubRange routine to learn more about subranges.

Examples

MtxVec.CreateIt(out a, out b);
With TVec(Self) do
try
    {
        Ln(Base);  //First do it the normal way then fix the anomalies
        Mul(Exponent);
        Exp;
        a.FindIndexes(Exponent,@"=",0);
        b.Size(a.Length,Complex);
        b.Setval(1);
        Scatter(b,a);
    }
finally
    {
        MtxVec.FreeIt(ref a, ref b);
    }
