MATLAB: How to access workspace variables one by one using m-script

Question

Hello,

I would like to read all workspace variables into array and check whether the name of variable is Matlab keyword or not. For example, I have four variables in workspace(a = 1;b=2;c=3;d=4;). I want to check if the varaible is keyword or not using matlab inbuilt function(iskeyword()) like below.

iskeyword('a')
ans =
       0
>> iskeyword('if')
ans =
       1

Is it possible check all base work space variables like this?

Answer 1

You can get all the workspace variables like this:

>> varList = evalin('base', 'who');

Then check individual parameters:

>> iskeyword(varList{k})  % for k-th parameter
