ValueAt Method

Applies to

Summary

Returns the function value and its derivate at a given argument.

Syntax

Spline.ValueAt (
   arg As Double,
  [derivate As Double]
) As Double

Parameters

arg
[in, optional] Double
derivate
[in, optional] Double

Remarks

The ValueAt method calculates the function value and its derivative at the given argument specified by the arg parameter. The arg parameter can be any value in tolerance range for a spline function (i.e. the B value should be positive for the BH-curve of soft magnet steel and so on).

The calculated value is returned as a function result. If the optional output parameter derivative is given, it takes the value of function derivative.
