MATLAB Function Reference

ver - Version information for MathWorks™ products

Graphical Interface

As an alternative to the ver function, select About from the Help menu in any product that has a Help menu.

Syntax

ver
ver product
v = ver('product')

Description

ver displays a header containing the current MathWorks product family version number, license number, operating system, and Java™ VM version for MATLAB. This is followed by the version numbers for MATLAB, Simulink, if installed, and all other installed MathWorks products.

ver product displays the MathWorks product family header information followed by the current version number for product. The name product corresponds to the directory name that holds the Contents.m file for that product. For example, Contents.m for the Control System Toolbox resides in the control directory. You therefore use ver control to obtain the version of this toolbox.

v = ver('product') returns the version information to structure array, v, having fields Name, Version, Release, and Date.

Remarks

To use ver with your own product, the first two lines of the Contents.m file for the product must be of the form

     % Toolbox Description
     % Version xxx dd-mmm-yyyy

Do not include any spaces in the date and use a two-character day; that is, use 02-Sep-2002 instead of 2-Sep-2002.
