<p>New features in AGSM version 2.3: </p>
<p>1 Robustness of closed contour fitting is dramatically improved by smart initialization (see InitialCircle.cpp). </p>
<p>2 Line fitting is compared to Hough transform and RANSAC least squares. </p>
<p>3 Circle fitting is compared to circle Hough transform. </p>
<p>New features in AGSM version 2.2: </p>
<p>1 We made the AGSM Canvas app more robust by smart initialization and image padding.
<br />
<br />2 Only one app for both 64-bit Windows and 64-bit Mac. </p>
<p>New features in AGSM version 2.1: </p>
<p>1 We added the AGSM Canvas App, which is an interactive software. </p>
<p>New features in AGSM version 2.0: </p>
<p>1 We added the line fitting and circle fitting packages. </p>
<p>2 We re-implemented GVF in C++/MEX to make it much faster. </p>
<p>3 We implemented Bresenham algorithm in C++/MEX to generate points on a line. </p>
<p>4 All force/torque computations are re-implemented in C++/MEX, which significantly improves efficiency. </p>

It was originally designed for data that was measured in a 3D grid of data points, for example temperature or wind speed taken at each point in a 3D space. If this data is taken over time, it can also be animated. However any data that fits the form v = f(x,y,z) or v = f(x,y,z,t) can be used.</p>
<p>If you have any ideas for enhancements or find any bugs, please let me know below. I'm open to adding more options/features if people find this useful.</p>
<p>Please use the 'Watch this file' option on this page to get auto updates when I add/fix things in the app.</p>
<p>Current version tested with 64-bit R2013b on Windows 7, should work on other platforms as well. The source code for the app is now included as well. You can try to run this on older versions that do not support apps by running the DataExplorer class file. You will need to add the GUILayout-v1p12 folder and subfolders to your path.</p>Adam Filionhttp://www.mathworks.com/matlabcentral/profile/authors/2429191-adam-filionMATLAB 8.2 (R2013b)MATLAB243232775837679falsetag:www.mathworks.com,2005:FileInfo/263372010-01-10T20:27:41Z2012-12-11T15:36:16ZAutoTune ToyAllows you to record and graphically manipulate and pitch correct your voice.<p>The AutoTune Toy was written to demonstrate pitch correction using Matlab. To be exact, I was watching Nova one night on PBS and there was a segment on Antares AutoTune software. I thought “I can do that in Matlab!” so this is my attempt at just that. This tool allows you to record short segments of your voice and interactively correct the pitch. Given that the tool uses memory to store the audio data, it is only practical to record short (20 second or less) audio fragments, but it is still a lot of fun to play around with!</p>Carlhttp://www.mathworks.com/matlabcentral/profile/authors/786865-carlMATLAB 8.0 (R2012b)Sound card and microphonefalsetag:www.mathworks.com,2005:FileInfo/235262009-04-02T08:34:46Z2012-09-12T00:30:36ZWaveform Generator GUIGenerate waveformed signal and play it. Interactive GUI with movable datapoints.<p>It is part of DJ toolbox project: <a href="http://dj-toolbox.9f.com/">http://dj-toolbox.9f.com/</a>

<br />It define form of one period of signal. It is possible to move points with mouse.
<br />Nearest, linear, spline interpolations method are used. It is possible to make continius signal.
<br />Sound can be played or saved to wav file. Window is resizable.

In most cases additional constraints are to be entered as well.
<br />
<br /> Example:
<br />
<br /> Input:
<br />
<br /> x points : [1 2 3 4]
<br /> y points : [2 7 -1 5]
<br /> Order : 2
<br /> *One Additional Constraint is Required*
<br /> f '' (1) = 0
<br />
<br /> Output:</p>
<p> Polynomials:
<br /> 0 5 -3
<br /> -13 57 -55
<br /> 27 -183 305
<br />
<br /> In the Range:
<br /> 1 2
<br /> 2 3
<br /> 3 4
<br />
<br /> This means the following:
<br />
<br /> for 1 < x < 2 y = 0*x^2 + 5*x - 3
<br /> for 2 < x < 3 y = -13*x^2 + 57*x - 55
<br /> for 3 < x < 4 y = 27*x^2 - 183*x + 305</p>Husam Aldahiyathttp://www.mathworks.com/matlabcentral/profile/authors/1477385-husam-aldahiyatMATLAB 8.0 (R2012b)Acknowledged file MATLAB Earthquake (Optional)22816false
