RegModels.LineEval Method ([In] double[], [In] TVec, [In] TVec)
RegModels Class  RegModels Members  Dew.Stats.Units Namespace  LineEval Method  Example  See Also
Collapse All

Evaluates b[0] + b[1]*X for given values in X vector, parameters in B array, and returns the results in XHat vector.

Syntax
C#
Visual Basic
public static void LineEval([In] double[] B, [In] TVec X, [In] TVec YHat);
Remarks

Size and Complex properties of XHat vector are adjusted automatically. 

Note Use this version if you want to evaluate linear function for multiple values at the same time. This is a lot faster than calling single value version for each x value.

Example

Evaluate linear function for multiple values at the same time. 

 

using Dew.Math; using Dew.Stats.Units; namespace Dew.Examples { private void Example() { Vector X = new Vector(100,false); Vector Y = new Vector(0); X.Ramp(-5.0, 0.1); RegModels.LineEval(new double[] {1.0, 3.0}, X, Y); } }
