ocmath_z_minmax

Description

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

Syntax

uint ocmath_z_minmax( const d_complex * pData, uint i1, uint i2, 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

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_z_minmax_Ex1()
{
    vector<complex> v={1 +2i,2+2i,3+3i,4+4i,5+5i,2+2i,3+3i,4,15+2i,3,3,4,3,3};
    v[7].m_re= NANUM;
    
    uint     nMin,nMax;
    uint     nMissingValues=ocmath_z_minmax(v, 2, 14, &nMin, &nMax);
    printf("%d %d %d\n", nMissingValues, nMin, nMax);
    //nMissingValues=1    nMin=14 nMax=8             
}

Remark

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

pnmin and pnmax if supplied must point to buffer of GECE_SIZE, see oc_const.h for GECE_REAL to GECE_AMPL

pData is considered missing values if either real or imaginary part is missing value (NANUM)
