Combining the capabilities of both EISPACK and LINPACK (for linear equations) into a single framework. Why EISPACK Still Matters
Routines are modular, allowing users to calculate all eigenvalues, only a subset within a range, only the eigenvectors, or both. The Systematic Approach: The "Driver" Philosophy
By the late 1980s, the architecture of computers had changed. The rise of cache memory and vector processors meant that the "point-to-point" memory access patterns of EISPACK were no longer optimal. This led to the development of (Linear Algebra Package). LAPACK superseded EISPACK by:
