***File called***
Contains companion tech report entitled:
Wavelet Tranform Algorithms for Finite-Duration Discrete-Time Signals.
This tech report was written in 1991, revised in 1993, and will be published in
1994 in the Association for Computing Machinery's Transactions on Mathematical
Software. For continued work related to the 1991 tech report, see "Wavelet
Transform Algorithms for Finite-Duration Discrete-Time Signals" pages 221-224
