22 Aug 2011 Circular Statistics Toolbox (Directional Statistics) Compute descriptive and inferential statistics for circular or directional data. Author: Philipp Berens

Good toolbox! I added a function for kernel smoothing density estimate for circular data here: http://www.mathworks.com/matlabcentral/fileexchange/32614-kernel-smoothing-density-estimate-for-circular-data .

02 May 2014 Read Unicode Files Reads Unicode strings from file, outputs character array of strings Author: Vlad Atanasiu Stiritz, Brad

Very helpful function, thank you! One small issue needs to be fixed, however. Running the function with one argument only (the file name) generates a run-time error..

------------------------------------------
>>textscanu(file_spec);
Error using close (line 136)
Invalid figure handle.

Error in textscanu (line 141)
close(h)
------------------------------------------

This error results from:
(a) setting the waitbar handle to default value (0) in the switch block beginning on line 59.
(b) not checking (h) against the "magic" default value (0) before trying to close in line 141.

The simplest fix is to replace line 141 with the following code block:

------------------------------------------
% close waitbar if created
if h ~= 0
close(h)
end
------------------------------------------

However, I should point out that it's not a good choice to use (0) as the default value for (h), since (0) can be a valid handle in general. Better to use (NaN) as the default value, since:

------------------------------------------
>> ishandle(0)
ans = 1

K>> ishandle(NaN)
ans = 0
------------------------------------------

A safer way to code the function would be to initialize (h) to (NaN) before the initial switch block, then re-assign h = waitbar(..) within case 5. The conditional block at the end of the function should then be:

------------------------------------------
% close waitbar if created
if ishandle(h)
close(h)
end
------------------------------------------

23 Oct 2013 Kernel smoothing density estimate for circular data Provides various methods to smooth circular data. Author: Vlad Atanasiu Muir, Dylan

A couple of issues with this function: firstly, the circular stats toolbox functions called by this function assume radians as input, while this function uses degrees in its examples.

Secondly, this function requires that the vector of angles over which to calculate the kernel density estimate is identical to the domain of periodicity. If this condition is not satisfied, the function fails badly. This requirement should at the very least be mentioned in the help, and ideally removed entirely.
