how to use while loop to access workspace values?

I have some value in my workspace. i want to access those value one by one using while loop. so i can find a value which is greater then x. Any help would be grateful

You're almost certainly better off re-structuring your data so that you don't have to iterate through the variables in your workspace. Try storing the values in a sequential array instead.

However, if you REALLY want to do this, you can do as follows:

 variables = who;

 for i = 1:length(variables)

   eval('A = ', variables{i}); %A now stores the i-th variables info
    %do stuff to A like A > x or whatever

end

Again, don't do this! It's a bad idea. Restructure your code so you can just loop instead without using eval and dealing with the workspace.
