Interpolation is correct for grid, but wrong for random points

I am using scipy interpolation to construct a map of two coordinates to two other coordinates --- effectively one set of coordinates are 2D cartesian coordinates (called X and Y), and the other are ...

I find myself having difficulties to get a concrete coordinate representation of the contangent lift of the configuration space of a mechnanical system. Setupwise, we have a vector field $X \in TQ$ ...

Nondifferentiable coordinate transforms

Suppose that we have coordinates $u=u(x,y)$ and $v=v(x,y)$ in $\mathbb{R}^2$ so that $v$ is not differentiable when $u(x,y)=u_0$ where $u_0$ is a constant. Can we solve a differential equation, such ...
