Problem combining ParametricNDSolve with NonlinearModelFit
I am finding some inconsistencies in getting NonlinearModelFit to work with the output of ParametricNDSolve. Here is an example that works (starting with a fresh Kernel): eqs = {a'[t] == -k1 a[t] - k2...
View ArticleHow to do 3D plot using ParametricNDSolve with do loop?
I want to make a 3D plot of E1 and E2 ( notice) they are depends of four parameters w, w1, t1 ,and t2, as shown E1 = -(2/w) Log[0.2] (1/w - t1) ((w^3 Log[1 - 1/w^3] - w^-3 + 1) - w^2) E2 = w1/2 (w1/2...
