Example
This example creates an expression with an array of constant values.
object[,] knownY = {{2.0, 3.0, 9.0, 1.0, 8.0, 7.0, 5.0}};
object[,] knownX = {{6.0, 5.0, 11.0, 7.0, 5.0, 4.0, 4.0}};
FarPoint.CalcEngine.Expression arg1 = new FarPoint.CalcEngine.ArrayExpression(knownY);
FarPoint.CalcEngine.Expression arg2 = new FarPoint.CalcEngine.ArrayExpression(knownX);
FarPoint.CalcEngine.Expression[] args = new FarPoint.CalcEngine.Expression[] {arg1, arg2};
FarPoint.CalcEngine.Expression func = new FarPoint.CalcEngine.FunctionExpression(FarPoint.CalcEngine.FunctionInfo.SlopeFunction,args);
