Hi Soeren,<br>
This is not really a matter for the GRASS PSC. When the PSC approves SVN commit access for a developer he/she is then permitted to make changes in SVN as he/she sees fit. Technical issues are in general resolved by achieving consensus on the developers' mailing list, and the PSC only arbitrates as a last resort if consensus cannot be achieved. I think in this instance Hamish suggested it might be a PSC matter because of the licensing issue - but the simple solution is to re-licence the LGPL code as GPL when it goes into GRASS, to keep everything under the same licence (but as I said this is IMHO a matter for the developers' list...)</blockquote>

<br>
Just to be clear - the GRASS PSC doesn't interfere in technical development issues<br>
Hope this is helpful<br>

Dear PSC,<br>
i would like to make an proposal to include parts of the ccmath* library<br>
into grass to replace the following numerical recipes algorithm in grass:<br>
<br>
Located in gmath library:<br>
1.) Computation of eigenvalues in eigen_tools.c.<br>
2.) Linear equation solver in lu.c<br>
3.) Singular value decomposition in svd.c<br>
<br>
The library will be located at grass_src/lib/ccmath.<br>
I will patch all effected modules in GRASS.<br>
A new gmath test suite will provide tests for most of the ccmath functions<br>
which will be available in GRASS.<br>
<br>
The ccmath library is licensed under the LGPL. I will assure that every<br>
ccmath file includes a LGPL header information and the name of the original<br>
author.<br>
I will place a lgpl.txt license file in the ccmath library directory.<br>
<br>
If my proposal will be accepetd, i will commit the changes to the svn<br>
development<br>
repositories of grass6.5 and grass7.<br>
<br>
Best regards<br>
Soeren Gebbert<br>
