Hello, and I stand corrected. I also should have said "ancient" Greek
mathematicians. I'll stand by my comments on Wikipedia. I'm an EE by
profession and none of my applied math textbooks mention "permanent".
Other matrix properties/type such as determinant, inverse, diagonal,
trace, skew, hermetian, eigenvalues) are dealt with in detail, however.
