Area Square

A collection of functions for calculating the upslope area and related measurements for a digital elevation model (DEM).Based on the method of Tarboton.See also the upslope area postings on my image processing blog, March-August 2007, http://blogs.mathworks.com/steve.Requires Image Processing...

FASTRMS Instantaneous root-mean-square (RMS) power via convolution.FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the same size as X and contains, for each point in X, an estimate... Platforms: Matlab

This demo plots a simple figure and a small rectangle (gray) area. The position of the area can be interactively moved and resized interactively (in a standard "windows" way). When the area is double clicked, the figure is zoomed according the area. The double click outside the area resizes the... Platforms: Matlab

This routine will shade the area of a 2-D plot between two user defined vectors. Simply pass the two vectors, and their corresponding horizontal coordinates, select your fill color and transparency level and viola! You have a figure that is colored in between the two input vectors. Platforms: Matlab

JaLaM is short for "Java Local Area Messenger". That means, it is a Java-based chat for your local network (e.g. in your office). There is no need for a server, because JaLaM uses UDP-Broadcasts to find other clients inside your local network. Features: No Server needed No installation, just... Platforms: Mac

The Link Area module provides an "area plugin" for Views 3. It allows customized links to be placed in the header, footer, or empty text of any view.The obvious use case is to create a list of all nodes of type "foo" and then add a header link to the node/add/foo page. By making it a real link... Platforms: PHP

This functions displays GUI for selecting square or rectangular part of the input image IMG. To perform selection user must click mouse twice: at two corners of the selection area. User can change the shape at any moment, even when first point is set, unless it is not forbidden by additional... Platforms: Matlab

Poker Square is played with a deck of 52 standard playing cards. 25 spaces aligned in a 5 by 5 grid are used for this game. At the start of the game, all spaces are empty and the player takes one card at a time from the stock and place it onto the grid. The goal of the game is to form the best... Platforms: Mac

fitChiSquare is a generalized chi-square fitting routine for any model function when data measurement errors are known; it returns the model parameters and their uncertainties at the delta chi-square = 1 boundary (68% confidence interval). It also returns the chi-square and degrees of freedom... Platforms: Matlab

This program displays the contour plot of an mxn (m ~= n) matrix, and then calculates the area for regions above a given level. This is a brute force implementation. It probably has some bugs, and there are probably more elegant ways to do this, but it does what I need. I am open to feedback on... Platforms: Matlab

fcnHomogeneousMaskAreaFilter performs noise filtering on an image based on searching for the most homogeneous mask within a search area around a pixel of interest. The method uses a square neighborhood of 5x5 pixels with 3x3 masks to estimate the gray-level homogeneity in each of the masks. The... Platforms: Matlab
