Hi, @robot0321, @myavartanoo, @Reyhanehne
I understand what the _pd_full function of the Shape3DModel class in model.py is doing, but I cannot understand what _gen_polycoeff_center is doing? Intu…

作者您好,关于SFC3D部分,我有一些问题想跟您请教:
1. 在LineSegment.m函数中,第39-42行的含义您能讲解一下吗?我所理解的是在第38行中dir是直线的方向向量,而39行中的dir_h应该是切平面的法向量,它应该是平行于dir的?并且切点pp1等应该是 最大椭球与障碍物相切的切点,为什么要用例如第46行这样的表达去计算呢?
2. 在LineSegment.m函数中,第89-…

It would be rather convenient if there existed methods to easily create matrices with special structure, e.g., Toeplitz, Vandermonde, and Moore matrices. Not sure where these should go though. `matric…

Dear :santa:
Please edit and add new features at will (not saying everything should be implemented for `v1`):
- [x] More user friendly MRA initialization, e.g. `world_size = [-20, 20]**3`
- [ ]…

Still peroxide supports only real number. But for many cases, complex number, vector & matrix should be required.
- [x] Integrate `num_complex::Complex`
- [x] Complex vector
- [x] Re-design `Vec…

This comes from a discussion with @TobiaMarcucci
Currently our `Polynomial` class is written as a linear combination of monomials `∏xᵢᵈⁱ`. As mentioned in the previous literature, monomials are "b…

Symbolic expressions may be part of type-neutral computations, e.g. matrices, polynomials. Developers do not expect proof machinery to crank up when writing `if x!=0`, but this is just what happens.…
