Usage
Tests for the existence and non-emptiness of a variable.
the general syntax for its use is
y = isset('name')
where name is the name of the variable to test. This
is functionally equivalent to
y = exist('name','var') & ~isempty(name)
It returns a logical 1 if the variable is defined
in the current workspace, and is not empty, and returns
a 0 otherwise.
