I purchased the Linux home version plus the parallel computing toolbox. Home version installed, how can I tell if the parallel computing toolbox installed?

There are two things you can check:
ver('distcomp') %this tells you whether it is _installed_
license('test','Distrib_Computing_Toolbox') %this tells you whether it is _licensed_
It is a pain that you have to know the exact magic names and that the names are different for the two facilities.

Awesome. Thanks. The code to check for my particular program ended up being:
try
ver('distcomp')
catch
fprintf('Not installed')
end

J, use the ver command.
You should see something like
Parallel Computing Toolbox Version 6.6 (R2015a)

Thanks. For runtime, I want to check only for the Parallel Computing Toolbox. I tried ver product, ver(product), ver('product'), and tried finding a function specific to the Parallel Computing Toolbox, but failed and so using
if true
% code
n = 'dss';
pat = '(?<=^.+[\\/]toolbox[\\/])[^\\/]+';
regexp(which(n), pat, 'match', 'once')
end
failed as well. Do you happen to know what format product name should be in for the Parallel Computing Toolbox? Thanks.

Novice user here. An online search found the function canUseParallelPool(). My PC does not have Parallel Computing Toolbox installed. As expected, the function returns False on my installation

@Mark that's close. canUseParallelPool was introduced in R2020b and in the unlikely event the a user set the parallel preference to not automatically start, canUseParallelPool will return false as well.
If you look at the code, canUseParallelPool shows you a possible way to determine if Parallel Computing Toolbox is installed and licensed.
I'd probably use @Walter Roberson's solution, though programmatically, I'd wrap isempty around the call to ver.
