C application programs are about three times larger
than C++ application programs
that do vector and matrix arithmetic.

You could implement
The Scalar, Vector, Matrix and Tensor class library

on top of the GNU Scientific Library (GSL).
But I am disinclined to do so myself right now.
Any application that depends upon the GSL will break
if the GSL library developers make any changes
in the data representation or algorithm implementation.
I also fear that the GSL developers may abandon the GSL
before it is completed like Robert D. Pierce
abandoned the GNU Scientific Software Library (GNUSSL).

I can't even get the GNUSSL to compile anymore.
