  • How do I compute derivative using Numpy? - Stack Overflow
    scipy interpolate's many interpolating splines are capable of providing derivatives So, using a linear spline ( k=1 ), the derivative of the spline (using the derivative() method) should be equivalent to a forward difference
  • Calculating a derivative with Math. NET C# - Stack Overflow
    Building the spline is easy, and the Akima spline looks to be nice and smooth through the points If you wanted a method that takes in a set of data and returns the derivatives, here's an example using the AlgLib math library:
  • How do I compute the derivative of an array in python
    numpy diff(x) computes the difference between adjacent elements in x just like in the answer by @tsm As a result you get an array which is 1 element shorter than the original one
  • Implementing the derivative in C C++ - Stack Overflow
    Typically signal noise impacts the derivative quality more that anything else If you do have noise in your f(x), Savtizky-Golay is a excellent smoothing algorithm that is often used to compute good derivatives In a nutshell, SG fits a polynomial locally to your data, the then this polynomial can be used to compute the derivative Paul
  • What is the difference between SQL, PL-SQL and T-SQL?
