The spectral basis and its order are inferred from the initial guess. - Fs (list of callables): The right-hand side of the ODE and its derivatives. I.e. Fs[0] is F, - Fs[i] is d^i F / dx^i. The order of the equation n is determined by + Fs (list of callables): The right-hand side of the ODE and its variational derivatives. I.e. Fs[0] is F, + Fs[i] is δF / δu^(i). The order of the equation n is determined by the length of Fs minus one. Each callable must accept 3 parameters: - a numpy array containing the values of x - - an iterable of n numpy arrays containing the values of F and + - an iterable of n numpy arrays containing the values of u and its derivatives at x - a tuple of additional parameters passed to nonlin_solve_1d as args args (tuple): Extra parameters passed to the Fs. |
