User Operand

When using a ZOSAPI-based user operand, a "Prog#" of 0 performs the calculation, while any other value retrieves the specified value from the result vector.

double Hx = TheApplication.OperandArgument1;    //  Hx
double Hy = TheApplication.OperandArgument2;    //  Hy
double Px = TheApplication.OperandArgument3;    //  Px
double Py = TheApplication.OperandArgument4;    //  Py
int dataLength = TheApplication.OperandResults.Length;
double[] results = new double[dataLength];
for (int i = 0; i < results.Length; ++i)
{
    double x = i;
    double x2 = x * x;
    double x3 = x * x * x;
 
    results[i] = Hx * x3 + Hy * x2 + Px * x + Py;
}
//
//  Now assign the locally calculated resule back to the Application.
//
TheApplication.OperandResults.Data = results;

NOTE: that the interface allows an arbitrarily large vector, however only the first 100 values will be stored and accessible by OpticStudio.
