Mar 26, 2012 · How do I calculate the derivative of a function, for example y = x2+1 using numpy? Let's say, I want the value of derivative at x = 5...

Jan 8, 2009 · I have some expressions such as x^2+y^2 that I'd like to use for some math calculations. One of the things I'd like to do is to take partial derivatives of the expressions. So if f(x,y) = x^2 + y^...

Aug 26, 2010 · To calculate the derivatives using Savitzky-Golay smoothing filter, the polynomial coefficients computation has a parameter b, the value b [derivative] must be set to 1.0, the array be …

I'm interested in computing partial derivatives in Python. I've seen functions which compute derivatives for single variable functions, but not others. It would be great to find something that did...

May 18, 2015 · Is there a way to get scipy's interp1d (in linear mode) to return the derivative at each interpolated point? I could certainly write my own 1D interpolation routine that does, but presumably …

May 4, 2017 · I would like to get a symbolic form for the third order derivatives (which would be a tensor) -- is there a way to do that in Wolfram Mathematica? EDIT: I should mention, A and C are matrices, …

Aug 27, 2021 · I am having a problem of plotting my derivatives. For example of my equation: The value of x = 3 f(x) = 6x^2 - 2 f'(x) = 12x f (3) = 36 from scipy.misc import derivative import matplotlib.pyplot a...

Sep 30, 2022 · The problem is not with derivatives — contrary to what you believe, they are well-defined on the edges. Nor is the lack of anisotropic filtering — because it happens at non-oblique angles too.

Sep 6, 2011 · The number of derivatives for each dimension (because it follows a binary pattern) is (2^dim)-1; e.g., 2^3 = 8 - 1 = 7. The derivative that is dyx is the dx value of the adjacent points in the …
