Testing Matlab compatibility of exist()

[Rik]

6/25/14

Could someone run the following code bits under Matlab?

s.a = 1;
tmp = exist ('s')
tmp = exist ('s.a')

And a second test.  Create a blank file 'sin' in the current working
directory (which I assume is on the Matlab path()).

tmp = exist ('sin')

Thanks,
Rik
