Description

Removes elements having the missing value (NANUM) from the right end of the vector.

Syntax

int TrimRight( BOOL bDelExtra = FALSE )

Parameters

bDelExtra: [input] TRUE will delete cells on the right of (after) the last valid numeric value, FASLE will cause the upper bound or index to be adjusted downward but no cells are deleted.

Return

Returns -1 on error, >=0 on success, and N > 0 for number of cells deleted.

Examples

EX1

void vectorbase_TrimRight_ex1()
{
    // The current window is Worksheet with two columns
    Worksheet wks=Project.ActiveLayer();
    if (wks)
    {
        Dataset dsA(wks,0);
        Dataset ds1(wks,0), ds2(wks,1);

        dsA.TrimRight(TRUE);

        Curve crvAxBy(ds1, ds2);
        crvAxBy.TrimRight(TRUE);

        LT_execute("doc -uw");
    }
}

EX2

void vectorbase_TrimRight_ex2()
{
    vector vecData = {0.1,0.2,0.3,0.4};
    vecData[2] = NANUM;
    vecData[3] = NANUM;
    //Source data: vecData = {0.1,0.2,NANUM, NANUM};

    vecData.TrimRight(true);
    //Result Data:   vecData = {0.1,0.2};
}

Remark

TrimRight removes elements having the missing value (NANUM) from the right end or bottom of vectorbase derived objects by retarding the upper index to the last valid numeric value. If bDelExtra is set to TRUE cells containing NANUM are deleted from the vectorbase object. When bDelExtra is TRUE TrimRight of Curve objects causes both X and Y Datasets to be trimmed.
