FFTW non-symetric inverse transform c2r
Suppose I have a real 2D matrix A(MxN), by using the FFTW3 r2c transform I take the matrix into Fourier space where B is the complex array B=fft(A(Mx(N/2+1))).
I know that B has Hermetian redundancy, so I perform some operations (left-right, up-down…

storing a matrix as a collection in MongoDB
I have a bunch of points {A, B, C, ...., X} and I want to store their distances in a matrix. One extra complication is that the distance from A to B and not the same as the distance from B to A, they are asymmetric.
My aim is to store this matrix…

Asymmetric nearest-neighbour in Java
From a sorted map, I want to retrieve a subset of n entries, starting m entries before a specified value v. For example, for the key set k = {0.2, 0.3, 0.4, 0.6, 0.8, 0.9, 1.0}, a query with n=5, m=2, v=0.5, would return {0.3, 0.4, 0.6, 0.8, 0.9}.…

Difference between symmetric and asymmetric matrix
I'm practising with graphs and adjacency matrices. But I couldn't find a good example that differentiates symmetric and asymmetric matrix. Can anyone tell me how to distinguish the difference between symmetric or asymmetric matrix.
