Data Points

Run the file main.m and everything works fine.The matrix A contains the data points and it can be changed in the file inputfile.m Platforms: Matlab

DataThief III is a program to reverse engineer data points from a graph. Typically, you scan a graph from a publication, load it into DataThief, and save the resulting coordinates, so you can use them in calculations or graphs that include your own data.. Platforms: *nix

This function fetches data points from matlab supported image formats and writes them into a specified text file. Use 'help d_fetch' for more details. Platforms: Matlab

(1) Use the mouse to click and drag the red data points within the dotted gray box, and observe the changes in the conic section in real time.(2) This function requires the symbolic math toolbox and is tested using Matlab version 7.1 (R14) service pack 3.(3) This function illustrates some...

OOK - On Off Keying, This is the Basic ASK Modulation , and remember to transmit at least (100/BER(theoretical)) data points Platforms: Matlab

This is the fastest (though not most accurate) method of fitting a circlle to data points on a plane (given by their xy-coordinates). It returns the circle center (a,b) and radius R. It was proposed by I. Kasa in article "A curve fitting procedure and its error analysis", IEEE Trans. Inst. Meas.,... Platforms: Matlab

The function interpolates between SRTM data points. Platforms: Matlab

A line of connected straight sections is fitted to a 2D-cloud of data points. The sections are described by the coordinates of their endpoints. No toolbox required. Platforms: Matlab

To find the intersection point of two data sets can be non-trivial in case of the data sets have just a few data points.In this case the both data sets can be interpolated so that there exist a number of data points large enough to find an intersection point.The find_intersection function... Platforms: Matlab

Fits a Gaussian curve to data points. You can specify your initial values for amplitude, mean and standard deviation, or it will guess them. Platforms: Matlab

Time::Skew is a Perl module that computes local clock skew with respect to a remote clock. SYNOPISI use Time::Skew # Init Convex Hull and timing data my $hull=[]; my $result={}; # Iterate data point introduction Time::Skew::convexhull($result,$datapoint,$hull); This module supports...

DataThief III is a program to reverse engineer data points from a graph. Typically, you scan a graph from a publication, load it into DataThief, and save the resulting coordinates, so you can use them in calculations or graphs that include your own data.It is written in Java.It is capable of... Platforms: Mac

[A , c] = MinVolEllipse(P, tolerance)Finds the minimum volume enclosing ellipsoid (MVEE) of a set of data points stored in matrix P. The following optimization problem is solved:minimize log(det(A))s.t. (P_i - c)'*A*(P_i - c) Platforms: Matlab

The fitting of smooth curve through a set of data points and extention to this is the fitting of 'best fit' spline to a large set of data points which show the cerrent trend but which do not all lie above the curve. The method involves cluster analysis, that is, grouping the crude data into... Platforms: Matlab

PGFHIST2D(X, Y, W) will save a PNG file representing the 2D histogram created from data points specified by X and Y with weights specified by W. The vectors X, Y, and W must have the same number of elements. The text to include in a Latex file to produce the histogram is displayed. Valid options... Platforms: Matlab

Plots data points and first through sixth degree polynomials. Displays polynomial coefficients and r-squared values in command window. Allows user to choose range. Also allows user to remove trendlines that don't appear to fit. Platforms: Matlab

This code helps to read data points from plots,first you need to calibrate this tool so that itcan convert pixel information into useful valuesfrom the plots.It asks you to click on the origin of the plot andenter the (x,y) value as shown on the plot. Then,it wants the reference points on the x... Platforms: Matlab

Given a set of data points, this function calculates the center and radius of the data in a least squared sense. The least squared equations are used to reduce the matrix that is inverted to a 3x3, opposed to doing it directly on the data set. Does not require a large arc or many data points.... Platforms: Matlab

Sometimes, rows or columns (or both) of a displayed matrix or vector have different meanings, and it would be nice to display them along with the matrix (instead of, say, remembering that the third row holds a given property of a set of data points). This function allows you to specify strings... Platforms: Matlab

This GUI converts an image of a curve into data points relatively quickly, even if the original image contains grid in the background.The way to use it is very simple. 1)open an image 2)choose scale parameters 3)choose Image processing parameters (default values can often be sufficient) 4)Start...
