Syntax

ver product
product_info = ver(product)
ver -support

Description

ver displays:

  • A header containing the MATLAB® product family version number, license number, operating system, and version of Java® software for the MATLAB product.

  • The product name, version number, and release name for MATLAB and all other installed products.

Use ver to checks which MATLAB products are installed and their version number. To check the current MATLAB release information including update number use the matlabRelease function instead.

example

ver product displays the header and the version number and release name for product, where product is the name of the folder that contains the Contents.m file.

product_info = ver(product) returns product information to the structure array, product_info.

example

ver -support displays licensing information for your installed products. Use this command when completing a customer support case form. This syntax is not recommended for programmatic use.

Create a structure containing version information for just the Symbolic Math Toolbox™ product. The output shown here is representative. Your results might differ.

Determine the product name for Symbolic Math Toolbox by setting n to the name of a function unique to Symbolic Math Toolbox, such as sym.

n = 'sym';
pat = '(?<=^.+[\\/]toolbox[\\/])[^\\/]+';
regexp(which(n), pat, 'match', 'once')

ans =

symbolic

Specify the value returned in the previous step as an argument to ver.

v = ver("symbolic")
