ocmath_b_sum
Description
Calculate the vector's sum, minimum and maximum.
Syntax
double ocmath_b_sum( BYTE * pData, uint nSize, BYTE * pmin = NULL, BYTE * pmax = NULL, uint * pnmin = NULL, uint * pnmax = NULL )
Parameters
- pData
- [input] buffer containing data
- nSize
- [input] size of pData
- pmin
- [output] the minimum element of pData
- pmax
- [output] the maximum element of pData
- pnmin
- [output] index of pmin
- pnmax
- [output] index of pmax
Return
Sum of all the elements of pData
Examples
EX1
void ocmath_b_sum_ex1()
{
vector v={1,2,3,4,5,2,3,4,54,3,3,4,3,3};
uint nSize=14;
double dMin, dMax;
uint nMin,nMax,nCount;
v[7]=NANUM;
double dsum=ocmath_d_sum(v,nSize,&dMin,&dMax,&nMin,&nMax,&nCount);
printf("%f %f %d %d %f %d", dMin, dMax, nMin, nMax, dsum, nCount);
//dMin=1 dMax=54 nMin=0 nMax=8 dsum=90 nCount=13
}
