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

Pascal
function FindIndexes(const a: TMtxVec; const op: string; const b: TCplx): TMtxVecInt; overload;

Example

Ensure that the power function will return 0, if the exponent is 0.

CreateIt(a,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 FreeIt(a,b); end;
