Many estimation functions use numerical differentiation with respect to the model parameters to compute their values.
The numerical differentiation is a typical inverse problem, it is known to be ill-posed in the sense of Hadamard that small perturbations in the function to be differentiated may lead to large errors in the computed derivative. based on MATLAB that we discuss four kinds of arithmetic in the ...

Thenumdifftools packageforPythonwas written by Per A. Brodtkorb based on the adaptive numerical differentiation toolbox written inMatlabby John D'Errico[DErrico06]. Later the package was extended with some of the functionality found in the statsmodels.tools.numdiff module written by Josef Perktold...
Numerical integration of areaI admit, I always forget, since trapz tries to be tricky. You can call it with 1 or 2 arguments. With 2 arguments, you call it as trapz(x,y), but with only one argument, it is just trapz(y). Personally, I never liked the way they did it.
The strains were estimated from the video in Matlab over a 5 × 7 point grid (area 12.5 × 17.5 mm2) using the method described in [13]. In Matlab functions‘nomrcorrx()’ [15] and ‘dftregistration()’ [16] (code provided by the first author in Github) were used to extract displ...
