2%GB_SPEC_TYPE determine the class of a MATLAB matrix
3% s = GB_spec_type (X) determines the class of X.  It is identical to s =
4% class(X), except when X is a complex matrix.  In this case the string
5% 'complex' is appended to the result of class (X).  If X is a single and
6% iscomplex (X) is true, then s is 'single complex', and if X double, s is
7% 'double complex'.  Complex integer matrices result in 'int8 complex' (for
8% example), although GraphBLAS does not currently handle those.
