- what do the interpolationmethods ‘cubicspline’ and ‘from_derivatives’ do?
Interpolate data with a piecewise cubic polynomial which is twice continuously differentiable The result is represented as a PPoly instance with breakpoints matching the given data scipy interpolate BPoly from_derivatives Construct a piecewise polynomial in the Bernstein basis, compatible with the specified values and derivatives at breakpoints
- Whats the best way to calculate a numerical derivative in MATLAB?
This can be used to calculate approximate derivatives via a first-order forward-differencing (or forward finite difference) scheme, but the estimates are low-order estimates As described in MATLAB's documentation of diff (link), if you input an array of length N, it will return an array of length N-1
- Vulkan: Creating and benefit of pipeline derivatives
I came to this question investigating whether pipeline derivatives provide a benefit Here's some resources I found from vendors: Tips and Tricks: Vulkan Dos and Don’ts, Nvidia, June 6, 2019 Don’t expect speedup from Pipeline Derivatives Vulkan Usage Recommendations, Samsung Pipeline derivatives let applications express "child" pipelines as incremental state changes from a similar "parent

- python - How should I get derivatives from scipy RBFInterpolator . . .
I've found RBF gives much smoother 2D interpolation results than B-Splines via scipy interpolate bisplref with my particular data, but I need to take derivatives of what I get When I evaluate the B-Splines using scipy interpolate bisplev, I can specify dx and dy to get any order of derivative in each dimention
- c++ Eigen: spline derivatives () gives strange derivatives
The derivatives seem to be multiples of the "true" derivatives In the x^2 case, they are 5 times what they should be, in the x^3 case they are 8, 12 and 16 times as big respectively
- how to get derivatives from 1D interpolation - Stack Overflow
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 scipy'
