RBio: Version 1.1.2, May 1, 2009. A MATLAB Toolbox for reading/writing sparse
matrices in Rutherford/Boeing format.
To install, cd to the RBio directory and type "RBinstall" in the MATLAB
command window. RBio is written in Fortran because the Rutherford/Boeing
format can require Fortran I/O statements, depending on how the files are
stored. Files created by RBio do not require the Fortran I/O library to read
them, however.

MATLAB help for RBio:
--------------------------------------------------------------------------------
RBio - MATLAB toolbox for reading/writing sparse matrices in the Rutherford/
Boeing format, and for reading/writing problems in the UF Sparse Matrix
Collection from/to a set of files in a directory.
RBread - read a sparse matrix from a Rutherford/Boeing file
RBreade - read a symmetric finite-element matrix from a R/B file
RBtype - determine the Rutherford/Boeing type of a sparse matrix
RBwrite - write a sparse matrix to a Rutherford/Boeing file
RBraw - read the raw contents of a Rutherford/Boeing file
RBfix - read a possibly corrupted matrix from a R/B file
RBinstall - install the RBio toolbox for use in MATLAB
Example:
load west0479
C = west0479 ;
RBwrite ('mywest', C, 'WEST0479 chemical eng. problem', 'west0479')
A = RBread ('mywest') ;
norm (A-C,1)
See also UFget, mread, mwrite.

Note that the west0479 matrix provided in the Test directory is the correct
version. The MATLAB statement "load west0479" gives you a matrix that is
slightly incorrect (as of MATLAB Version 7.3, R2006b).
