Can the script detect the version of MATLAB on which the script run?

I write a script that depends on a new feature of R2020b. But other people may not have R2020b. Is it possible to write such as

if (the version is R2020b)
    run hello_R2020b.m
else if
    run hell_R2020a.m
end

?

How can one find out the version number of R2020b?

WTP?

A = ver('matlab')
A = 
  struct with fields:

       Name: 'MATLAB'
    Version: '9.9'
    Release: '(R2020b)'
       Date: '29-Jul-2020'

Why you think you need to use run, I cannot imagine, but whatever floats your boat.
