So the problem is to numerically solve this Integro-Differential Equation,
$$-v \frac{\:\mathrm{d}\kern0.1mm x(\zeta)}{\:\mathrm{d}\kern0.1mm \zeta} + \psi(\zeta) x(\zeta) + \int_{0}^{\zeta} f(\zeta, \eta)x(\eta)\:\mathrm{d}\kern0.1mm \eta + g(\zeta)x(1) = 0 \\$$
where $v$ and $x(1)$ are known co...
So, I'm using NDSolve to approximate the solution to a Schrodinger like equation
$i\psi_{t} + \psi_{xx} + \frac{1}{2}|\psi|^{2} \psi + \lambda \left( \left[|\psi|^{2} \psi\right]_{xx} + |\psi|^{4} + \psi \right) =0$
where $\psi: \mathbb{R}^{1+1} \to \mathbb{C}$. To do this I've modified the co...

I'm calling out the users m_goldberg, yohbs, Cassini, ciao, and Jim Baldwin for putting my question on hold unfairly because according to them my last question had nothing to do with Mathematica. This other question of mine had nothing to do with Mathematica, but like the one before it, it was ab...
