Description

Compute the sum of all elements of the vector.

Syntax

int Sum( int & nSum )

int Sum( double & dSum )

int Sum( complex & cxSum )

Parameters

nSum: [output]sum of all elements of the vector for int type

dSum: [output]sum of all elements of the vector for double type

cxSum: [output]sum of all the elements of the vector for complex type

Return

Returns 0 on success or a non-zero error code on failure.

Examples

EX1

void vectorbase_Sum_ex1()
{
    // Sum elements of a vector of type short
    vector<short> vecS = {1, 2, 3, 4, 5};
    int iSum;
    vecS.Sum(iSum);
    out_int("iSum = ",iSum);
    // Result:
    //        iSum = 15
}

EX2

void vectorbase_Sum_ex2()
{
    // Sum elements of a vector of type double
    vector vecD = {1.1, 2.1, 3.1, 4.1, 5.1}
    double dSum;
    vecD.Sum(dSum);
    out_double("dSum = ",dSum);
    // Result:
    //        dSum = 15.5
}

EX3

void vectorbase_Sum_ex3()
{
    // Sum elements of a vector of type complex
    vector<complex> vecC = {1+2i, 3+4i, 5-6i};
    complex cSum;
    vecC.Sum(cSum);
    out_complex("cSum = ",cSum);
    // Result:
    //        cSum = 9 + 0 i
