Iteration

The file contains Lucas-Kanade Tracker with pyramid and iteration to improve performance. There is a wrapper for image sequences, and a corner detection function using Shi-Tomasi method.

It can handle iteration for all permutations, combinations, subsets and tuples.This is useful when the results of perms or nchoosek are too large to hold in memory but the number of iterations is feasible.Vectors are ordered according to number of elements and lex. if the length is the same, they...

x = LCP(M,q) solves the LCP x >= 0 Mx + q >= 0 x'(Mx + q) = 0 x = LCP(M,q,l,u) solves the generalized LCP (a.k.a MCP) l Mx + q = 0 x = u => Mx + q Mx + q > 0 x = LCP(M,q,l,u,x0,display) allows the optional initial value 'x0' and a binary flag 'display' which controls the display of iteration...

The program estimates a given number of intersection values, amongst which the start point of the following iteration can be chosen. These values are found graphically, and after each ended iteration the found intersection value is plotted with a cross together with the iterated function. This...

Funiter (short for function iteration) is an application developed for educational purposes as a laboratory, generating graphs of several types for iteration of real and complex functions, with comfortable switching between related types of graphs. Originally developed in the context of courses...

Often a loop performs calculations where each iteration of the loop does not depend on the previous iteration, and the iterations really could be carried out in any order. This module allows you to run such loops in parallel using all the CPUs at your disposal. Return values are automatically...

Example of usage: >>> from croniter import croniter >>> from datetime import datetime >>> base = datetime(2010, 1, 25, 4, 46) >>> iter = croniter('*/5 * * * *', base) # every 5 minites >>> print iter.get_next(datetime) # 2010-01-25 04:50:00 >>> print iter.get_next(datetime) # 2010-01-25 04:55:00...

You want to make a mixture. You have ingredients composed of the same components. The proportions (percentage,content) of the components is different in each ingredient. The composition of the mixture will depend on how much of each ingredient you will add. Exact this -"how much of each...

This function provides a simple iterator for the lines of a file-like object. (It also provides a flag for removing/retaining trailing newlines.) I ran into the problem a number of times that I wanted to read-in a very large file-like object (say a GB or two) line by line. This is a problem for...

This is a single M-file that implements a Nelder-Mead simplex minimizer. It makes use of MATLAB's persistent variables to create a "state machine" implementation. This allows entire minimization programs to be written as MATLAB scripts, as it does not require a function to be defined and passed...
