Example Of Idempotent Matrix

if else example is a basic example of an if then else control structure.

Breadth first traversal of tree script is an example of the self-recursive generators. The first argument should be the tree root; children should be a function taking as argument a tree node and returning an iterator of the node's children.

This script is an example of how to use the winreg module. The code had the first purpose of demonstrating the concept of a graphical shell built in Python. The shell was easily modified to make use of the Window's registry but retains traces of its original method of operation.

The code uses array indexing to implement shifting of the matrix. It is about 2.5 times faster than using interp2 with 'nearest neighbor' option for shifting of the matrices. Inspiration for optimized array indexing comes from a snippet on circular shift in: "MATLAB array manipulations tips and...

Up to now, to find the first non-zero element of a matrix along a column (for example) user might:1. Use for-loop with FIND command for j=1:size(A,2) ... = find(A(:,j), 1, 'first'); end 2. Use other vectorized methods, often time not very straight-forwards (MAX, LOGICAL, SPARSE, etc...). This...
