OK, makes sense.

What packages or binding to which library should one use in Ada
to use sparse matrices?

In Matlab, almost all build-in functions that work with normal matrices,
also work as in with sparse matrices. Makes life very easy.

To solve Ax=b, even when A is sparse, one can still write A\b.

Is it possible to do something like this in Ada? There are number
of sparse libraries out there, but googling around, do not see
an Ada binding at this time.

I think Ada is much behind when it comes to ready to use functions
and libraries for computational science. Too bad, since the language
itself is probably the best for this sort of thing.
