22 Jul 2013 local_time_to_utc Convert local time to UTC Author: Peter Tenenbaum

It's a pity I found this submission only after having written my own one (inferior to this one, since only working on Windows).

06 Feb 2013 Optical Fibre Toolbox Simulation of optical fiber modes Author: Kotya Karapetyan

I apologize that I cannot answer each comment here. The two-layer model implemented in the OFT has been thoroughly checked numerous times. It has been used for a couple of years now to compare against our results in various experiments. Plus it was used to verify the three-layer model, whenever possible. No mistakes have been found in the recent time, the two-layer code is stable. Therefore I am pretty sure there are no mistakes in that part of the code. Mistakes (typos) do occur in books and papers however. Also, different notations and/or assumptions can be made, e.g. concerning the coordinate system or polarisation direction.

Robert, I have just downloaded OFT from this page and run demo/oftDemo.m with Matlab 2009b and 2012b. In both cases it has completed without problems.

23 May 2012 DataHash MD5 or SHA hash for array, struct, cell or file Author: Jan Simon

It would be nice to be able to check the returned values against some public results. For example Wikipedia mentions MD5("") = d41d8cd98f00b204e9800998ecf8427e and MD5("The quick brown fox jumps over the lazy dog.")
= e4d909c290d0fb1ca068ffaddf22cbd0, and I don't know how to get the same from DataHash to check it.

13 Sep 2014 Flickr API with OAuth-based user authentication Matlab implementation of Flickr-compatible OAuth Author: Kotya Karapetyan Maxwell Agnew

Works very well, even for other APIs

30 Aug 2013 Flickr API with OAuth-based user authentication Matlab implementation of Flickr-compatible OAuth Author: Kotya Karapetyan Stephen

Thank you very much!

I think there might be a mistake.

In the file modeField.m
according to Snyder's book
m is odd, it is HE mode
f=sin(nu*phi); g=cos(nu*phi);

But in your code,
f = @(nu,phi) cos(nu*phi);
g = @(nu,phi) -sin(nu*phi);
