Write C Programs to Read MAT File Data - MATLAB & Simulink (original) (raw)

Main Content

Read and write MATLAB® data from C programs, using mxArray

When you program your entire application in MATLAB or when you share data with other MATLAB users, use these MATLAB procedures.

• To bring data into a MATLAB application, use Supported File Formats for Import and Export.
• To save data to a MAT file, use Save and Load Workspace Variables.

There are situations, however, when you must write a custom program to interact with data. For example:

• Your data has a custom format.
• You create applications for users who do not run MATLAB, and you want to provide them with MATLAB data.
• You want to read data from an external application, but you do not have access to the source code.
