2.1.24.4.42 ocmath_row_quantiles

Description

get input matrix's each row's min, max, 1st Quartile, median and 3rd Quartile and put result to relative pointer if the pointer not NULL.

Syntax

OCMATH_API int ocmath_row_quantiles(UINT nRows, UINT nCols, const double* pMat, double* pMin = NULL, double* pMax = NULL, double* pQ1 = NULL, double* pMedian = NULL, double* pQ3 = NULL, int nInterpolate = INTERPOLATE_WEIGHT_AVER_RIGHT)

Parameters

nRows

[input] row number of input matrix.

nCols

[input] column number of input matrix.

pMat

[input] pointer to input matrix which will be get quantiles.

pMin

[output] if not NULL, pointer to each row's min value, its size should be nRows. Its default value is NULL.

pMax

[output] if not NULL, pointer to each row's max value, its size should be nRows. Its default value is NULL.

pQ1

[output] if not NULL, pointer to each row's 1st Quartile, its size should be nRows. Its default value is NULL.

pMedian

[output] if not NULL, pointer to each row's miedian value, its size should be nRows. Its default value is NULL.

pQ3

[output] if not NULL, pointer to each row's 3rd Quartile, its size should be nRows. Its default value is NULL.

Return

return OE_NOERROR on success, else return minus error code.

Examples

EX1

void ocmath_row_quantiles_ex1()
{
	vector vtemp = {1, 2, 3, 4, 5, 6};
	int nRows = 2;
	int nCols = 3;
	vector vMin(nRows);
	vector vMax(nRows);
	vector vQ1(nRows);
	ocmath_row_quantiles(nRows, nCols, vtemp, vMin, vMax, vQ1);
}
// At the end of example: vMin = {1, 4}, vMax = {3, 6}, vQ1 = {1, 4}.
