-----------------------------------------------------------------------
The file sid3 documents sis3 in the style of the other SVDPACK files. 
Please review this file before using the sis3.f program.
-----------------------------------------------------------------------

Here are the other files/directories included in this tar file.

sis3.f   (contains main program, and ritzit)
op.f     (contains matrix-vector mult. routines: opa, opb)
LAPACK/  (all lapack files are in this directory)
BLAS/    (all blas files are in this directory)
sii3     (sample input file for sis3)
sio3     (sample ASCII output of one run of sis3)
sio.stats(convergence statistics output in ASCII)
makefile (typing "make" should create library.a and sis3 binaries)
matrix   (374 by 82 sparse test matrix read by sis3.f; this is the
          same matrix contained in the file "lai7" from SVDPACK)
README   (this file)

The file: ./makefile should be modified so that the variable "TOP" is
set to the correct (current) directory. Also, ./makefile, BLAS/makefile,
and LAPACK/makefile assume that the fortran compiler: f77 is valid. This
should be modified when this is not the case.  If your machine
has optimized LAPACK and BLAS libraries you should link those kernels
in rather than compiling and linking the subroutines here.
