Listing of Development Tools in Scripts

Embed/Hide one or more images inside one bigger image (source image). Code also tells how much of the source image you are using for embedding and as long as it's less than 100 percent, you can obviously cramp in more images. Hide n seek!!.

This program simulates the problem of sorting the pages of a file on a disk.Suppose we have 100,000 pages in a file in a database then if we have to sort records of this file,then we can do it with 3 buffer pages only and that too in only 17 passes.This program will create sorted intermediate runs(files) and finally a single run(file) with all the records in all the pages n the disk sorted.

This script may be easily converted to a function which could be an extremely useful subroutine in optimization problems to check whether the objective function is globally convex. It may also be used to derive the expressions for gradient and Hessian of the given multidimensional real valued function along with giving their values at the point entered.

This routine calculates the median squared error of a linear function, and can be used with fminsearch as a robust linear regression (see help LinearMedianSquaredError). It should be very easy to extend the example code to handle nonlinear functions and to minimize other error functions (least absolute error, for instance).

This module is useful for running complex 3rd party programs in the backend to analyze/process data stored in the Drupal database. Through Drupal admin interface, you simply issue any pre-defined data processing commands into a queue, which are executed later by the 3rd party programs (perhaps on a remote server) asynchronously.

This is a Matlab implementation of a unique algorithm by J. D. Opdyke with very good properties for solving the Integer Composition problem of finding all permutations in the additive partitioning of integers. It also accepts lower and upper bounds for the number of sum terms as well as lower and upper parts for the sum term values.

This function amplifies areas of high intensity and segments them using a front. The front is initialized on the convex hull (for speed) and erodes the map until it has converged on the edge of the areas to keep, maintaining edge geometry. The idea and title for this function come from Dr.

(SE) is developed to estimate the number of clusters (NC) for PAM clustering algorithm. By inspecting whether it is stable that two potential clusters are separated or merged, SE focuses on the separability of two closest clusters among k potential clusters (called twin-clusters) when a data set is divided to k clusters.

Instead of starting with dark blue like Jet, this colormap starts with white. It goes to pure blue from white, and then continues exactly as Jet does, ranging through shades blue, cyan, green, yellow, and red, and ending with dark red. The attached picture shows how colormap can display some types of data better than the built-in Jet.

SPECGRAMSCOPE makes it fairly easy to include a spectrogram scope in your real-time data acquisition and analysis application. You feed spectrumscope your data, and it plots the FFT - simple enough! It takes 2 steps to use SPECGRAMSCOPE. First, you initialize the scope with basic information needed for the FFT (sample rate, fft length, and history length).

When doing traditional bode diagram control system analysis of ill-conditioned high order SISO systems in V4.2 with Control System Toolbox, I found using these utilities improved the robustness of my results. There's also a nice function to plot an approximate (asymptotic) bode diagram which I find helps me visualise a transfer function's poles and zeros slightly better than with an exact bode diagram.

With legendflex, you can: - position the legend relative to any object in any figure, not just the parent axis of whatever is being labeled - organize legend text and symbols in a grid with a specified number of rows and/or columns - rescale the horizontal space used by each legend symbol - create multiple legends for the same axis - add a title to the legend within the legend box.
