05 May 2011 list, queue, stack implement the list, queue, stack data structures in matlab Author: Zhiqiang Zhang

I makes two updates (waiting for moderation)

1. add an method "isempty" to determine if the stack and queue is emtpy, and the method "emtpy" is to remove the content of the stack and queue. (thanks to Vojtech)
2. throw a warning when top an empty stack, and back, front an empty queue. throw an error when pop an empty stack and queue. (Thanks to Derek)
04 Dec 2010 Binary Search Binary search of values in a data vector. Author: Aroh Barjatya

The function used fliplr and flipud who are terrible for the usage: we are using binary search to get log(n)-time efficiency, but both of the functions are linear.

If your algorithm is linear, we prefer ind = find(x==var) rather than your algorithm.
06 Oct 2010 extract substring substr extracts a substring of length len from the string str, starting at the specified offset. Author: Phillip M. Feldman

simple but nice code
02 Oct 2010 String comparison Compares 2 strings. Output is identical to that of C string library. Author: ChinSoon Lim

02 Oct 2010 explode_implode Two functions: split string into pieces, join strings with delimiter in between. Author: Sara Silva

SPLIT = strread(STRING,'%s','delimiter','DELIMITER') ;
doesn't work well. It trum off the space at the beginning of the pieces.

22 Feb 2012 backup and sync backupfolder - backup a folder, syncfolder - sync folders, revertbackup - revert previous backups Author: Zhiqiang Zhang Michal

Hi, when I want execute syncfolder, I´ll get this error:

??? Undefined function or method 'strcmpc' for input arguments of type 'char'.

Error in ==> syncfolder at 93
elseif nf1 <= numel(files1) && ...

My syntax is:

syncfolder('Z:\folder1\','C:\Users\Me\Documents\folder2\',1)

Do you have any suggestions to solve this problem. Thanks a lot!
