check Matlab tlbxs availabe and license

As mentioned and recommended in the https://stackoverflow.com/a/2061547/15905792

One drawback to the ver function is that it only tells you what's installed, not what has an available license. It's possible to have a toolbox installed and no license to use it (or all the available licenses could be checked out by other users). A better choice is the license function, which (as you pointed out) requires a unique "feature string" for each toolbox.

The following code checks for licenses for the entire list above:

index = cellfun(@(f) license('test', f), featureStr);
availableFeatures = featureStr(logical(index));

and

index = cellfun(@(f) license('checkout', f), availableFeatures);
checkedOutFeatures = availableFeatures(logical(index));

Unrecognized function or variable 'featureStr'.

Unrecognized function or variable 'availableFeatures'.

How to correctly check available toolboxes and its available licenes?

featureStr={'MATLAB','Simulink'}

featureStr = 1x2 cell array
    {'MATLAB'}    {'Simulink'}

index = cellfun(@(f) license('test', f), featureStr)

index = 1×2

1 1

<mw-icon class=""></mw-icon>

<mw-icon class=""></mw-icon>

availableFeatures = featureStr(logical(index))

availableFeatures = 1x2 cell array
    {'MATLAB'}    {'Simulink'}

OK. how to get all that up-to-date featureStrings list?

There is a function getFeatureName(fullname) in this thread. I tried it and it worked well.
