In finite element formulations, one will usually end up with sparse matrice= s. I do not know whether Ada has support for such matrices. Matlab for inst= ance has dedicated solver(s) for the system Ax=3Db when A is a sparse matri= x. I think beside storage consideration, sparse matrices solvers are faster= (I can be wrong though). There was a discussion in one posts on CLA here some two years back about s= parse matrices. Forgotten which thread it was though. YC=20
