SciPy-5 B-Spline CurvesInterpolate bank, which is in the SciPy, provides lots of ways to do the interpolation operation. Here is an example of interpolation with directed line and B-Spline to fix the point on 2016-08-28 SciPy Python SciPy
SciPy 4 SciPy: fsolveSciPy: fsolve-2We can solve the nonlinear equation by Jacobian determinant(matrix). For the question in fsolve-1, the Jacobian matrix of f to u is :$$\begin{bmatrix}\frac{\partial f_1} {\ 2016-08-28 SciPy Python SciPy
SciPy 3 SciPy : fsolveWe use the scipy.optimize.fsolve to solve the nonlinear equations. The basic format is fsolve(func, x0). In the format, func(x) is the function of error in equations. The parameter x is 2016-08-25 SciPy Python SciPy
SciPy-2 SciPy : fminscipy.optimize -> fmin -> fmin, fmin_powell, fmin_cg, fmin_bfgs y(output) = x(input) * h(convolution) deconvolution : y, h -> x We use fmin to realize the deconvolution. 2016-08-25 SciPy Python SciPy
SciPy-1 SciPy 1Least-square fittingFor database (x[i], y[i]), we know there is functional relation called y=f(x), we know the f(x) as the f(x) = f(x, p), p is the set of undetermined coefficient. We need to k 2016-08-24 SciPy Python SciPy
