I have a 2D matrix corresponding to the shown image in Cartesian coordinates. In image, the horizontal axis is x and vertical corresponds to y-axis. How to change this 2D matrix to polar coordinate system using mathematica ?Read more

Suppose $ X_t$ is a Feller process and $ q(x,\xi)$ is the symbol of $ X$ , which satisfies $ $ \lim_{t\downarrow 0} {\bf E}_x \frac{f(X_t)-f(X_0)}{t}=-(2\pi)^{-d/2} \int_{\mathbb{R}^d} e^{ix\cdot\xi}q(x,\xi)\hat{f}(\xi)\ d \xi, $ $ for all $ f\in C^\infty_c(\mathbb{R}^d)$ . Assume $ $ \sup_{x\in \mathbb{R}^d}|q(x, \xi)|\leq C(1+|\xi|), \quad\forall\xi\in \mathbb{R}^d $ $ and $ \Gamma\subseteq \mathbb{R}^d$ with $Read more

I am trying to animate THETA value in a polar plot but it shows an error.Please help me. Here is the equation: Animate[PolarPlot[{1/(1 + 0.5*Sin[(a/b) \[Theta] – Pi/4])}], {a, 1, 10,1}, {b, 1, 20, 1}, {\[Theta], 0, c Pi}, AnimationRunning -> False]Read more

OVERVIEW Seeking pointers to Mathematica based visualization examples that are “close to” the attached graphic of data from a 24 hour period of measurements. DETAIL I am looking to replicate a 1977 era graphic in Mathematica. The attached image plot is a multi-attribute display of datums collected over a 24 hour period of time. TheRead more

Hi, I am looking at the above question and I have made an answer, but upon looking back I realised that I assumed that we would be integrating wrt $ \theta$ from $ 0$ to $ 2\pi$ because we are converting to cylindrical coordinates, but I don’t know if I can make that assumption. MyRead more
