Simple interpolation class

Interpolation was a need for several reason. Here we show to you simple interpolation class by using linear interpolation.

public class Interpolate
 {

     // Value1 ValueNeed Value2
     //
     // Value3 Result1   Value4

     public double Interpolate1(double Value1, double Value2, double Value3, double Value4, double ValueNeed)
     {
         double Result1 = ((ValueNeed - Value1) * (Value4 - Value3) / (Value2 - Value1)) + Value3;
         return Result1;
     }

     // Value1    Value2
     //
     // ValueNeed Result1
     //
     // Value3    Value4

     public double Interpolate2(double Value1, double Value2, double Value3, double Value4, double ValueNeed)
     {
         double Result1 = ((ValueNeed - Value1) * (Value4 - Value2) / (Value3 - Value1)) + Value2;
         return Result1;
     }

     // Value1     ValueNeed Value2
     //
     // ValueNeed2 Result4
     //
     // Value3     Result3   Value4

     public double Interpolate3(double Value1, double Value2, double Value3, double Value4, double ValueNeed, double ValueNeed2)
     {
         double Result3 = ((ValueNeed - Value1) * (Value4 - Value3) / (Value2 - Value1)) + Value3;
         double Result4 = ((ValueNeed2 - Value1) * (Result3 - ValueNeed) / (Value3 - Value1)) + ValueNeed;
         return Result4;
     }
 }

Description

1. The above coding used for simple linear interpolation.
2. There are three option of interpolation available here which is base on the position of interpolation you need. This interpolation also can be used to interpolate from table.
3. Method to used it,  just create class for this interpolation and call it !!
