Updates 
24 Jan 2006 

I forgot to enable backwards compability for the included matFiles. Now the matFiles also work with Matlab V6.x
Thanks to Marie Ekstrom for bug reporting. 
06 Feb 2006 

A big in adding the right zone identifier was found for usage with utmcoordinates when transforming from ellipsoidal to projection coordinates.
I'm sorry for that. 
03 May 2006 

The Projections.mat file now is also accessible for Matlab R13 users. 
16 Feb 2007 

I was asked by Matlab users without geodetic background to give additional information about the transformation steps and an example of usage. I therfore added a paper which explains the calculations and gives a short introduction.

1.1 
I was asked to add a function which allows to calculate the transformation parameter set for cartesian datum transformation from two coordinate lists in both systems. 
18 Dec 2009 
1.2 
There was some confusion with the additional file helmert3d which did not transform righthanded coordinate systems but lefthanded, so the parameter sets did not fit in trafo3d.
this has been fixed now. 
25 Mar 2010 
1.3 
A leftout transposecommand rose an error in trafo3d with only two input parameters. Thanks to Jon Preston for noticing me. 
07 Dec 2011 
1.4 
The existing files of the Geodetic toolbox hove been completely revised and many additional functionality has been added. 
22 Dec 2011 
1.6 
Some minor changes in the existing functions were made. Additional transformation types have been added. 
24 Jul 2012 
1.7 
Update the coding error in d2affinetrafo.m Michael Schmitt mentioned on June 18th, 2012. Thanks, Michael! 
30 Oct 2012 
1.8 
A missing default was fixed in cart2ell.m
Thanks to Johannes SchĂ¶nberger to notice me. 
07 Jan 2013 
1.9 
In itrstrafo.m there was a mistyping of two variable names which have been corrected. Additionally, a set of transformation parameters from IGS2005 to IGS2008 has been added in Trafo_ITRF.mat 
07 May 2013 
1.10 
There were two small bugs in helmertprojective3d.m which threw errors. 
11 Nov 2013 
1.11 
Molodensky transformation added due to a user request. Minor bug in deg2dms fixed. In Matlab 2013b, helmert adjustments with worse normal equation matrices diverged while they converged in earlier versions. I changed that functions to overcome that. 
03 Apr 2014 
1.12 
Minor changes in the background document 
24 Jun 2014 
1.13 
Fixed some minor warning issues. 
20 Apr 2015 
1.14 
Andrea Pinna of the University of Cagliari sent me improvements of the helmert and helmertaffinefunctions which allowed to save a lot of memory and time. I am glad he offered me to update my toolbox with his improvements. Thanks! 
07 May 2015 
1.15 
Small Bug in helmert3d due to the latest chenges "x0 is not found" . 
26 May 2015 
1.16 
A mistyping was found in Helmert affine 3D transformation which is corerected now. 
20 Feb 2016 
1.17 
Two bugs were found in helmert3D's parameter adjustment.
Until the update, calculation took too many iteration steps and finally lead to resulats with errors ~ 1e14.
Thanks to Stefan Pegritz for the bug report!
