Assume I have a matrix. mat = {{1, 1, 8, 3, 5}, {2, 2, 6, 5, 3}, {3, 3, 9, 2, 7}, {4, 4, 7, 1, 7}, {5, 5, 3, 6, 8}, {6, 6, 8, 7, 7}, {7, 7, 2, 4, 4}, {8, 8, 9, 1, 6}, {9, 9, 1, 1, 2}, {10, 10, 2, 1, 6}, {11, 11, 6, 2, 4}, {12, 12, 9,…

Consider an implicit function like f dist[x_, y_] = Sqrt[(x - #1)^2. + (y - #2)^2.] & f[x_, y_] = dist[-1, 0][x, y] dist[1, 0][x, y] How to sample points on f[x,y]==c without explicitly solving for y? f[x,y]==c is a Cassini oval and looks…

Let's say I have two functions $f(x,y,z), g(x,y,z)$. I would like to know the probability that $f(x,y,z) < g(x,y,z)$ over some defined, numerical ranges of $x, y, z$. Any thoughts on how to do it besides nested for-loops? P.S. I have more than 3…

I have the data below. I would like to sample with equal step size. For simplicity lets try unit step size. Here is the desired result. Find the first time exceed the unit time step, and take lower ones second entry. …
