26 Apr 2013 Default arguments Set default values for optional function input. Author: Bas-Jan

What do you expect as result of this line:
varargin = varargin{:};
I assume, it should be deleted to avoid errors.
The code can be simplified:
varargout = defaults;
n = min(numel(defaults), numel(varargin));
varargout(1:n) = varargin(1:n);
if nargin > n
% error instead of a warning
end
An error is much more reliable than a warning, which will be overseen when a mutli-million line program fils the command window with status messages.
24 Apr 2013 Cell Array to CSV-file [cell2csv.m] Writes a cell array into a comma separated values text file (*.csv) Author: Sylvain Fiedler

This function has a large potential for improvements:
"var = eval(['cellArray{z,s}']);" could be replaced by the much faster and nicer "v = cellArray{z,s};".
"if size(var, 1) == 0" does not catch [1x0] arrays, while "isempty(v)" would.

Checking the success of FOPEN is strongly recommended to avoid a strange behaviour.

The documentation is sufficient and the function works as advertised.
22 Apr 2013 Fast String to Double Conversion str2doubleq converts text to double like Matlab's str2double,but up to 400x faster! multithreaded. Author: Lauri Tamminen

The idea is very good, but the results are not reliable. I cannot suggest to use this for productive work. A fair rating is not easy in this case, therefore I've hesitated for some years now.
22 Apr 2013 Convolution This function computes the convolution of two Discrete-time signals; x & y. Author: Ismail M. El-Badawy

Using "sum" as name of a variable shadows the built-in function with the same name. This results in troubles frequently.

What is the benefit compared to the built-in fast CONV command?

13 Feb 2013 DataHash MD5 or SHA hash for array, struct, cell or file Author: Jan Simon Nath

function handle refering to struct containing the function will create infinite loop. Is there any workaround ?

Exemple:

d= dynamicprops();
addprop(d,'f');
d.f= @(varargin) struct2cell(d);
DataHash(d.f) % infinite loop
09 Feb 2013 DataHash MD5 or SHA hash for array, struct, cell or file Author: Jan Simon Bose, Arindam

Hi, Do anyone have any idea, how to decrypt an MD5 code?
