TELESCOPING

Component integration systems. Preprocessing of component libraries can make it possible to produce specialized versions for use in contexts that might occur in programs that invoke these components. One preliminary study has made it possible to generate Fortran versions of a library for solution of large-scale eigenvalue problems (ARPACK) from a Matlab prototype. Our current system, called LibGen, produces eight different versions from each Matlab prototype routine, specialized on input matrix type (real versus complex, sparse versus dense, symmetric versus nonsymmetric).
