TOpenCLMtxVec.NormC Method (TOpenCLMtxVec, boolean)

The C-norm.

Pascal

function NormC(const Vec: TOpenCLMtxVec; RelativeError: boolean = false): double; overload;

C norm: ||V-Vec||, where V is the calling vector.

If the NormC is called without any parameters, the NormC calculates the norm of the calling vector. The C norm of ||V-Vec|| is defined by the formula:

If RelativeError is true then the computed norm is divided by the norm of V, and the function returns the "relative error":

Example

var a,b: TOpenCLVector; c: double; begin CreateIt(a,b); try a.CopyFromArray(TDoubleArray.Create(1,2,3,4)); b.CopyFromArray(TDoubleArray.Create(4,3,2,1)); c := a.NormC(b); finally FreeIt(a,b); end; end;
