scipy.integrate.solve_bvp(fun, bc, x, y, p=None, S=None, fun_jac=None, bc_jac=None, tol=0.001, max_nodes=1000, verbose=0, bc_tol=None)# 求解ODE 系统的边值问题。 此函数在数值上求解服从 two-point 边界条件的 ODE 的一阶系统: dy / dx = f(x, y, p) + S * y / (x - a...
而且至少对我来说，参与文档并不能真正清楚地解释如何使用solve_bvp。
SciPy中的函数integrate.solve_bvp用来求解下列形式的常微分方程(组): \frac{\mathrm d\bold y}{\mathrm dx}=f(x,\bold y,p)+S\frac{y}{x-a},\quad a\le x\le b\\ \text{bc}(\bold y(a),\bold y(b),p)=0\\ 其中bc表示boundary condition,即边界条件。 上式中,x是一个一维自变量,y...

Renamed 'res' to 'rms_res' in the return bunch. The name 'res' bothered me because of its ambiguity. Very minor, but still. Several fixes in the docstring. Another thing to consider: whether to allow *args, **kwargs parameters to pass into fun, bc, fun_

Boundary Value Problems: The scipy.integrate.solve_bvp() function can solve boundary value problems by providing a framework for problems with conditions specified at more than one point. Numerical Integration: In addition to solving differential equations, SciPy includes functions for numerical integratio...
