Using .NET from MATLAB

What Is the Microsoft .NET Framework?

The Microsoft .NET Framework is an integral Windows component that provides a large body of precoded solutions to common program requirements, and manages the execution of programs written specifically for the Framework. Read More

Displaying Graphics Images

Image Types and Display Methods

To display a graphics file image, use either image or imagesc. For example, assuming RGB is an image, Read More

Reading, Writing, and Querying Graphics Image Files

Working with Image Formats

In its native form, a graphics file format image is not stored as a MATLAB matrix, or even necessarily as a matrix. Most graphics files begin with a header containing format-specific information tags, and continue with bitmap data that can be read as a continuous stream. For this reason, you cannot use the standard MATLAB I/O commands load and save to read and write a graphics file format image. Read More

Matlab Annotation Objects and Example

Users typically create annotation objects from the Plot Edit toolbar or the Insert menu (select Plot Edit in the View menu to display the Plot Edit toolbar). However, you can also create annotation objects using the annotation function. Read More

Linking Graphs to Variables & Data Source Properties

Plot objects let you link a MATLAB expression with properties that contain data. For example, the lineseries object has data source properties associated with the XData, YData, and ZData properties. These properties are called XDataSource, YDataSource, and ZDataSource. Read More

Matlab Plot Objects

A number of high-level plotting functions create plot objects. The properties of plot objects provide easy access to the important properties of the core graphics objects that the plot objects contain. Read More
