Looking for simple matrix manipulation package in C.

[David R Kohr]

I'm looking for public-domain or freeware source for a simple
matrix manipulation package written in C.  At a minimum, the
package would need to contain routines for allocating and
deallocating variably-sized 2-dimensional arrays containing
"float" and "double" values (complex values would be a big
plus), duplicating one matrix's values into another, calculating
the inverse and transpose of a matrix, adding/subtracting/multiplying
two matrices, and adding and multiplying a scalar to each element
of a matrix.  We only have a "K&R" compiler, so the package
has to be written in "K&R" rather than ANSI C.

Pointers to the source for such a package would be greatly appreciated.
I'll summarize my finding to the Net if there is sufficient response.
(I have access to anonymous FTP, by the way.)
