ver - Version and license information for MathWorks products

Syntax

  • product_info = ver(product) example

Description

example

ver displays:

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

  • The version numbers for MATLAB and all other installed MathWorks products.

  • The license numbers for all installed MathWorks products if they differ from the MATLAB license number listed in the header. If a product is not recognized, or a license cannot be found, then the license is reported as unknown. If the license is a trial license, the term Trial instead of License appears in the output.

example

ver product displays, in addition to the header information:

  • The current version number for product, where product is the name of the folder that contains the Contents.m file for the product you are inquiring about.

  • The license number for product, if it differs from the MATLAB license number listed in the header.

example

product_info = ver(product) returns product information to structure array, product_info, with these fields: Name, Version, Release, Date, and Licenses. If a license is a trial version, the value in the Version field is preceded by the letter T.

Version and License for a Particular Product

Display version and license information for MATLAB and the Control System Toolbox product. The output shown here is representative. Your results may differ.

1. Determine the product name for Control System Toolbox by setting n to the name of a function unique to Control System Toolbox, such as dss:

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

ans=
control

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

ver control

Structure Containing Version and Licenses for the MATLAB family of products

Create a structure containing version and license information, and then display the structure values. The output shown here is representative. Your results may differ.

v=ver;
for k = 1:length(v)
  fprintf('%s\n', v(k).Name);
  fprintf('  Version: %s\n', v(k).Version);
  fprintf('  License: %s\n', v(k).Licenses{1});

Structure Containing Version and Licenses for a Particular Product

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

1. 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

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

v = ver('symbolic')

v = 

        Name: 'Symbolic Math Toolbox'
     Version: '5.8'
     Release: '(R2012a)'
        Date: '14-Sep-2011'
    Licenses: {'123456'}

Input Arguments

product

product-specific information

The product or toolbox for which you want to view version and license information, specified as a string.

To determine the string to use, run the following code, substituting the name of a product function for toolbxfcn:

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