- ## usage: strcmp (s1, s2)

- ## Compare two strings. Trailing blanks are significant.

- ## WARNING: Unlike the C function of the same name, this function
- ## returns 1 for equal and zero for not equal. Why? To be compatible
- ## with Matlab, of course.

- ## Why doesn't this always return a scalar instead of vector with
