Is it possible to use a variable name like this within Matlab?

I have standardized header names with slash like this: OXYGEN_UMOL/KG.
How do I escape the '/' so that I can use commands like this?
OXYGEN_UMOL/KG = 5;
The same variable name should go to my Excel writetable command.
Thanks!

It is not possible with regular variable names. The only time is may be possible is with the names of variables within a table, and then only in release R2019b. Unfortunately, I have R2019a so I cannot test this.

Confusingly, variable names can mean two different things now in matlab. A generic variable name, e.g.
>> A = 5
is limited to alphanumeric characters and _ and cannot start with a digit.
Since R2019b, table variable names on the other hand can have any characters in them, so yes a table variable can be named OXYGEN_UMOL/KG.
One way to do this:
>> t = table([1;2;3], ["aaa"; "b"; "cc"], 'VariableNames', {'OXYGEN_UMOL/KG', 'Name with spaces'})
t =
3×2 table
OXYGEN_UMOL/KG Name with spaces
______________ ________________
1 "aaa"
2 "b"
3 "cc"
Another way:
>> t.('#@!') = [10;20;30]
t =
3×3 table
OXYGEN_UMOL/KG Name with spaces #@!
______________ ________________ ___
1 "aaa" 10
2 "b" 20
3 "cc" 30
writetable will write these names as is in excel or a text file.
