The Vector module does not have support to perform integration of vector/scalar fields over curves, surfaces, and volume.
`Integral` class represents integration over variables. It cannot handle Ve…

Hello, I am conducting a 2D simulation by modifying the dip function in the source.cpp file to exp (- tt * tt/(2 * width * width)), which is a simple Gaussian function. As shown in the figure, when us…

I was trying to solve an integro-differential equation with periodic boundary condition. (toy problem)
```
K = @(x,y) exp(-sin(x-y));
A = chebop(@(x,u) diff(u) + fred(K,u),[0,2*pi]);
A.bc = 'pe…

Hi again :)
I'd like to bring up a topic that's been keeping me busy lately in the field of Physics-Informed Neural Networks (PINNS). During research I've come across a number of papers that discus…
