Version 2.1.1
 * Fix dropped $FFLAGS in Matlab install scripts

Version 2.1.0
 * Avoid potential memory leaks by changing how deallocation is handled
 * Enabled Matlab installation for MacOS and Windows
 * Corrected function names in Matlab documentation
 * Reduce precision of printed residuals
 * Make C examples consistent with Fortran examples

Version 2.0.0
 * Added support for using hsl_mi20 as a solver by including the mi20_solve
   routine.
 * Moved to new interfaces for different data types: mi20_setup_csr,
   mi20_setup_csc, mi20_setup_coord. Old mi20_setup interface still more
   efficient (in Fortran, not in C), but future plans will see this change.
 * MATLAB support improved to allow more than one instance of the
   preconditioner to be used at a time. The old pre 1.4.0 interface interface
   (previously deprecated) has now been removed entirely.

Version 1.6.0 Fix several undefined variable issues detected by nagfor.

Version 1.5.1 Fix Matlab installer bug so it now works with version 2012b.

2011-12-05  Jonathan Hogg
Version 1.5.0 Add C interface.

2011-10-24  Jonathan Hogg
Version 1.4.0 Update matlab interface to use handles.
Old matlab interface would require significant revision each time HSL_MA48
changed internal data formats, new one doesn't.
Also migrate to new hsl_matlab to make it possible to use gfortran and both
integer*4 and integer*8.
Also remove a stray non-conforming tab character from main source file.

Version 1.3.1
Work around potential compiler bug by replacing array slice notation
with do loops for several large copies.

2010-03-19
Version 1.3.0 Bug fixed in MI20_precondition
(several copies did not specify part of array to copy so could try
and copy unassigned entries)

2010-02-08
Version 1.2.0
Components of mi20_keep made public for use within hsl_mi20 matlab interface

2008-03-04
Version 1.1.2  Several lines > 80 reflowed with &s

2007-11-01
Version 1.1.1. Changed default for control%damping to 0.8
(on advice from Milan).

2007-10-17
Version 1.1.0
Added additional parameter control%reduction that allows the
coarsening to terminate if the reduction in size of successive
grids is too small.
