In the `Guide' component the reflectivity function is defined, on alpha, m, W, Qc, R0 parameters. But no one from them is considered in the description to the glasses the guide was maintained from. Could anybody hint me how should I calculate these parameters, or refer me to articles/papers/URL's, where this subject is discussed? Thanks a lot! -- WBR, Timur V.

If not then I'm sure it should be relatively trivial for me make one up for my specific case. In addition given the small size of the scripts would it be possible to come up with a method of producing both formats at output time, this would be convenient in view of the fact that we have Matlab server licence system that has a tendancy to run out of licences. thanks Robert Dalgliesh From peter.willendrup at risoe.dk Thu Nov 13 14:08:54 2003 From: peter.willendrup at risoe.dk (Peter Kjaer Willendrup) Date: Thu, 13 Nov 2003 14:08:54 +0100 (CET) Subject: [neutron-mc] Matlab and Scilab In-Reply-To: <37CAC51AC5C1D211966100A0C9ED000A043576A3@exchange07.rl.ac.uk> Message-ID: Hi Robert, On Wed, 12 Nov 2003, Dalgliesh, RM (Robert) wrote: > Does anyone have a method of converting between the Matlab and Scilab script > file formats produced at the end of a simulation? > > If not then I'm sure it should be relatively trivial for me make one up for > my specific case. > In addition given the small size of the scripts would it be possible to come > up with a method of producing both formats at output time, this would be > convenient in view of the fact that we have Matlab server licence system > that has a tendancy to run out of licences. I understand your point completely, we have a similar problem here at Risoe. (5 licenses for ~ 800 people!!! - A lot of these don't use Matlab ofcourse..) The latter of your option seems like a relatively clean solution - we will take a discussion about this on the dev team. Alternatively, a solution where the raw datafiles and the format headers are seperated would be possible. Cheers, Peter -- ------------------------------------- Peter Kjaer Willendrup, Cand.

It seems that someone did a lot of the needed work already, an m to sci .pl script exists. It is not fully doing what we want, but close. I am currently investigating how much more work must be done, and if this will provide the needed functionality.

I now have a more or less functioning tool which converts between Matlab and Scilab data formats. I am not giving this away yet, since a few things still need attention. ;) The plan is to include the sctipt (mcconvert maybe?) in the next release, which is comming out quite soon, probably around january 1st 2004.
