Solution:

For example, you can use verLessThan in the following manner to ensure that code requiring capabilities built into Simulink 6.3 (R14SP3) or later is run on one of the appropriate versions:
if verLessThan('simulink', '6.3')

error('MyCode:simulinkTooOld', 'Simulink 6.3 or higher is required.');

end
The next example shows how you can use verLessThan to write code that can run across multiple versions of MATLAB:

if verLessThan('matlab', '7.0.1')

% -- Put code to run under MATLAB 7.0.0 and earlier here --

else

% -- Put code to run under MATLAB 7.0.1 and later here --

end
Although this function is being introduced in MATLAB 7.4 (R2007a), you can download a version of the function from this solution that you can run on earlier versions of MATLAB (6.0 and later). You must be running MATLAB Version 6.0 or higher to use this M-file. Download the file and put it in a directory on your MATLAB path:

$MATLABROOT\toolbox\matlab\general

where $MATLABROOT in the MATLAB root directory as returned by the MATLABROOT function executed at the command prompt.

See the function reference page or M-file help on verLessThan for more information on how to use this function.
