Interactive input in Matlab

In Matlab (at least from the version 2009a) you can find the following interactive input functions:

They can be especially useful in the implementation of visual tracking of regions and objects in video sequences.

Basic scripts in Matlab

  • Convert a video file in ‘avi’ format in a sequence of ‘jpg’ files using Matla. [Link]
    • The  format of the output sequence of images can be easily changed.
    • It allows to custom the name of the output images.

Automatic documentation of Matlab files

M2HTML: Documentation System for Matlab in HTML [Link]

M2HTML is a powerful tool to automatically generate HTML documentation of your Matlab M-files. Its aim is to be a successor of the Perl script MAT2HTML from J.C. Kantor, including new features.

This toolbox includes the Template toolbox, thus allowing for a full customization of the output layout. It also uses the syntax highlighting engine from Highlight.m.

Doxyen filters for Matlab scripts [Link]

Ben Heasly has written a filter for doxygen that converts MatLab scripts (including the new object oriented features) into something doxygen can understand. An alternative filter is provided by Ian Martins. There is also one by Fabrice which can be found on Matlab Central.

XML interfaces for Matlab

XML Toolbox for Matlab  [Link]

The XML Toolbox for Matlab allows engineering users of Matlab to convert and store variables and structures from the internal Matlab format into human-readable XML format and vice versa. This format is required to be able to store parameter structures, variables and results from engineering applications in XML-capable databases and can be used for the transfer of data across the Grid.
The XML Toolbox is implemented as four small intuitive and easy-to-use Matlab function which can be called directly within the proprietary environment.
As an additional feature, this Toolbox allows the comparison of internal Matlab structures through comparing their XML representation, which has not been possible so far. 
This work originally began as a collaboration between Geodise and the DTI-funded GEM project at the Southampton Regional e-Science Centre. Current development has been funded as part of the OMII managed programme

XMLTree: an XML toolbox for MATLAB [Link]

XML Parser is an XML 1.0 parser written in MATLAB. It aims to be fully conforming. It is currently not a validating XML processor.
This XML Parser is embedded in a MATLAB class (@xmltree) including powerful methods to import, export, access and modify the data. A subset of XPath is used for addressing parts of the XML document.

XML Toolbox [Link]

The XML Toolbox converts MATLAB data structures of any level of nesting into an XML string. It also reads most types of XML strings/files and converts these into a Matlab structure.
