RBio: Copyright 2011, Timothy A. Davis, http://www.suitesparse.com
A MATLAB Toolbox for reading/writing sparse matrices in Rutherford/Boeing
format.

To install the MATLAB functions, cd to the RBio directory (the one containing
RBinstall.m, not the top-level directory) and type "RBinstall" in the MATLAB
command window.  To install the C codes, type "make" (requires Unix).  For
examples on how to use the C interface, see Include/RBio.h and Demo/RBdemo.c.

  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.

    west0479.rb	    sparse matrix west0479 from UF Sparse Matrix Collection
    west0479.rua    original Harwell/Boeing version of west0479

    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).
