3.1.6 Complex

Using Complex Values With Origin C Functions

Complex values can be passed into and returned from Origin C functions. The following Origin C code is a simple example.

complex myFunction(double x, int n, complex C)
{
    complex cc;
    cc.m_re = C.m_re * x;
    cc.m_im = C.m_im + n;
    return cc;
}

void testMyFunction()
{
    complex C1(4.5, 7.8);
    complex C2 = myFunction(1.2, 3, C1);
    printf("real == %f\nimag == %f\n", C2.m_re, C2.m_im);
}

Access complex Data from Worksheet

// make sure data type is complex in the second column in active worksheet window.
void GetComplexDataset()
{
	Worksheet wks = Project.ActiveLayer();
	if( wks ) // if active layer is Worksheet
	{
		Dataset<complex> ds(wks, 1);
			
		vector vPhase;
		int nRet = ds.GetPhase(vPhase);
		if( 0 != nRet ) // 0 for success
			printf("Fail to get phase");
		
		// add phase result to a new column
		Dataset dsPhase(wks, wks.AddCol());
		dsPhase = vPhase;		
	}
}

Access complex Data from Matrix

// make sure data type is complex in the active matrix window.
void GetComplexMatrix()
{
	MatrixLayer ml = Project.ActiveLayer();
	if( ml )
	{
		Matrix<complex> mat(ml, 0);
		
		matrix matPhase;
		if( !mat.GetPhase(matPhase) )
			printf("Fail to get phase");
	}
}
