When not sure if the variable is string or not, use:

"� help ischar

 ISCHAR  True for character array (string).
    ISCHAR(S) returns 1 if S is a character array and 0 otherwise.
 
    See also CHAR."

When using anything other than the basic data type in matlab (which is
a double), then things do not look so pretty any more. But almost 
everything in matlab is a double (ok, except strings). from the simple 
loop counter variable to the 20 MB sparse matrix to the index into an 
array of only 5 elements, they are all of type double as default.
