So are we...explain the use case of what you're trying to do.

If just want to create a valid MATLAB variable name,

genvarname('_x_1')
genvarname('%diff')
matlab.lang.makeValidName('%diff')

[Steven Lord]

But then to assign a value to it you'd need to do something we don't recommend.

Since the question is marked with release R2020a, if you can use a table array the variable names in a table don't need to be valid MATLAB identifiers.

>> t = table(42, -999, 'VariableNames', ["_x_1", "%diff"])
t =

  1×2 table

    _x_1    %diff
    ____    _____

     42     -999 

Retrieving those variables from the table requires a very slightly different approach than if the variable names were valid MATLAB identifiers.

>> y = t.('%diff') % The parentheses are required in this case

y =

  -999
