C# method for element by element difference of an array (derivative approximation)?

Question

I normally use python but am learning C#, is there a preexisting class in C# for getting an element-by-element difference of an array to basically get a derivative, like numpy.diff in python?

Answer 1

According to this page, numpy.diff does this:

>>> x = np.array([1, 2, 4, 7, 0])
>>> np.diff(x)
array([ 1,  2,  3, -7])

If this is the effect that you want to see, use LINQ:

var np = new [] {1, 2, 4, 7, 0};
var res = np.Zip(np.Skip(1), (a,b)=>b-a).ToArray();
