2.1.17.6.5 ocmath_norm

Description

The general norm funtion is to compute largest singular value for vector.

Syntax

double ocmath_norm( double * pData, uint nSize )

Parameters

pData

[input] pointer to vector data

nSize

[input] the size of data

Return

The largest singular value in vector. But if nSize < 1, return NANUM

Examples

EX1

int ocmath_norm_ex1()
{
    vector x(10);
    x.Data(1,10);//Generate data
    UINT nSize = x.GetSize();//get the size of data
    double svd = ocmath_norm(x, nSize);
    printf("The largest svd is %g\n",svd);
    return 1;
}
