Must be a strictly increasing sequence of real numbers with x[0]=a and x[-1]=b. y array_like, shape (n, m) Initial guess for the function values at the mesh nodes, ith column corresponds to x[i]. For problems in a complex domain pass y with a complex data type (even if the initial guess is purely real). WebMay 6, 2024 · since you are new to python, I suggest you look at the basic examples on how to use the odeint package and build your solution from there. It will take some time but your code will become more robust. That being said, there are many mistakes in the code.
