How to replace 'genvarname' with 'matlab.la​ng.makeVal​idName'?

Hi,

I'm using 'genvarname' to create variables names from strings. Example:

temp = 'abc'
v = genvarname(temp)
eval([v,'=5'])

Result

abc = 5

In Matlab 2017a I've got a suggestion to replace 'genvarname' with 'matlab.lang.makeValidName' as 'getvarname' will be removed from future releases. Could anyone help me with rewriting my example using 'matlab.lang.makeValidName'?

Creating or accessing variables names dynamically will make code buggy and slow, as a thousand discussions and threads on this forum have explained:

The documentation advises avoiding this as well:

The MATLAB blogs too:

If you want to learn to use use MATLAB efficiently then simply use indexing, and avoid bad practices like eval.

temp = 'abc'
v = matlab.lang.makeValidName(temp)
eval([v,'=5'])

Well, thanks a lot, but I'm a bit ashamed... I've tried that before but didn't work - seems I've made some mistakes. Thanks!
