Normal Gaussian Distribution

FractalTrees X is a program that draws somewhat realistic silhouettes of binary trees with a fractal structure. It allows you to interactively change the properties of the tree, like the broadness, fullness, and number of branches. You can also introduce normal (gaussian) randomness into the...

Sorts input matrix of data so that each column is re-ordered byuser-specified criteria. Options are (1) sort data by signal width (2)sort data by energy localization (3) sort data by dissimilarity ofdata to a normal probability distribution. The default option is toreturn all 3 options, as...
