TVec.FindMask Methods

Summary

Finds a vector mask.

Class
TVec

Declaration

Function FindMask(a: TMtxVec; op: string; b: TMtxVec): TVec;

Description

The b parameter is of AbstractMtxVec.TMtxVec type.

Declaration

Function FindMask(a: TMtxVec; op: string; b: TSample): TVec;

Description

The b parameter is of Math387.TSample type.

Declaration

Function FindMask(a: TMtxVec; op: string; b: TCplx): TVec;

Description

The calling vector will hold the those elements where the Op comparison between a and b is True. Op string parameter can be '<', '>', '>=','<=','=' or '<>'.

The calling vector will store the mask, 1 at those index locations where the Op comparison was True and 0 at those index locations where the Op comparison was false.

The calling vector stores the mask as Integers in to the memory location occupied by Values array. The memory is typecasted to an array of integers via IValues pointer. Other TVec methods can not be used to perform operations on an array of integers unless explicitly specified.
