I created a graph in spline type using Microsoft C# Chart tool. I have two root arrays which have double type elements; the first one is X array and the next one is Y array. The element of each X array corresponds to an element of Y array. Like at below. These arrays contain more than ten float or int values.
double [] X = …
double [] Y = …I want to find an interpolation value using Math.NET with any method. It can be linear, non-linear, regression, cubic or more complex.
I need the specific points between the X-Y data values which I used. I have known only the Y value of these points, but I can’t find the corresponding X value.
Most of the solutions have an error like “System.IndexOutOfRangeException occurred”. Therefore, I need a permanent solution.
