Sorry, I do not have access to a newer version than 4.2.2


code example:

thisVar = fullfile('./') % make a variable holding a [1x2] char 
c= exist(thisVar)


gives c=7 (so directory), while I expect to get c=1 as I am asking if a
variable exists.

if I do 


thisVar = fullfile('./')
c= exist(thisVar, 'var')
I get 
c=0

so it really does not think that thisVar is a variable.

so the function exist() seems to check the content of the variable?
