As indicated in the answer. The solution is simple, although perhaps unfortunate for you.
You cannot use a newer toolbox in an old release. Either you upgrade MATLAB to the new release, or you would need to write equivalent capability in the old release. But nobody else will do that for you. And the MathWorks cannot write code to support older releases when they release a new toolbox.
As such, if you really need that capability and cannot write it yourself, then you really need to upgrade your MATLAB release. As I said, this is perhaps unfortunate, but just how things work.
