Description

Find indices to min/max values and also to return the number of missing values in the given range.

Syntax

uint ocmath_us_minmax( const USHORT * pData, uint i1, uint i2, const USHORT * pMissing, uint * pnmin = NULL, uint * pnmax = NULL )

Parameters

pData: [input] pointer to vector data,
i1: [input] starting index to search for min max
i2: [input] ending index (inclusive) to search min max
pMissing: [input] Think as missing value, can be NULL if no missing values are defined
pnmin: [output] index to the found min value location
pnmax: [output] index to the found max value location

Return

number of missing values. If all values in range are missing values, then return (i2-i1+1). If none are missing values then returns 0

Examples

EX1

void    ocmath_us_minmax_Ex1()
{
    vector<float>     v = {1,2,3,4,5,2,3,4,54,3,3,4,3,3};
    v[7] = -1.23e-123;
    
    uint     i1 = 2, i2 = v.GetSize() - 1;
    float     dNam =-1.23e-123;
    uint     nMin,nMax;
    uint     nMissingValues = ocmath_f_minmax(v, i1, i2, &dNam, &nMin, &nMax);
    printf("%d %d %d\n",nMissingValues,nMin,nMax);
    //nMissingValues=1    nMin=5 nMax=8
