TMtxExpression::DefineComplex Method

TComplexValue *DefineComplex(const DewString &AVarName);

Defines new complex variable.

#	Name	Type	Description
1	AVarName	const DewString &

Remarks:

If variable with name AVarName already was definded, it will be redefined and all expressions which contain the symbol AVarName will be recompiled before the next evaluation.

Examples

#include "Math387.h"
#include "MtxParseClass.h"
#include "MtxParseExpr.h"
#include "Units.Math387.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units;

void Example()
{
    TMtxExpression* MyParser = new TMtxExpression();
    // 1. Define variables
    TComplexValue* z = MyParser->DefineComplex("z");

    // 2. Set values
    z->ComplexValue = Math387::Cplx(-2, 3);

    // 3. Add formula and evaluate,
    MyParser->AddExpr("2i*z");
    TCplx res = MyParser->EvaluateComplex();
    // res = -6-4*i
    delete MyParser;
}
