06 Jun 2011	Loader of a .txt file to a MATLAB matrix Loads a content of a .txt file and stores it in a MATLAB matrix Author: Luka	Hi Luka, welcome to the file exchange -- however there is already a submission called "txt2mat", http://www.mathworks.com/matlabcentral/fileexchange/18430-txt2mat . Would you please consider renaming (just) your .m-file? I think some users might get confused when they search the file exchange for txt2mat, especially since both files are to serve a similar purpose. Kind regards Andres
24 Nov 2010	txt2mat fast and versatile ascii data import capable of handling large text files Author: Andres	Hi arouabm Ben Mohamed, I'm sorry, txt2mat does not support mixed string/numeric output in cells as e.g. textscan does. It would be quite hard (probably) to change this without sacrificing speed and R13 compatibility. Btw, you can use some features of txt2mat (like line filtering) with read mode 'char' and use textscan afterwards (see example 3b). Perhaps, if ease of use is more important than speed, you may find the fex submission "readtext" useful as well.
16 May 2010	txt2mat fast and versatile ascii data import capable of handling large text files Author: Andres	Thanks for your feedback. Indeed it would be nice to have a handy column selection input argument instead of using 'ConvString' with something like '%f %f %f %f %f'. Regarding your memory issue, so far I can only refer to the 'NumericType' param and especially to example 6, but you probably found that in the doc already. txt2mat reads in the whole part of the file that is to be imported and initializes the output array. In an extreme case, a double array holding the data may consume about four times more memory than the file, unless some rows have missing values. I am thinking about making txt2mat more memory efficent - e.g. avoid slurping large files - without noticeably loosing speed (but tbh I have hardly any spare time now).
08 Apr 2010	txt2mat fast and versatile ascii data import capable of handling large text files Author: Andres	It would be most simple if you could uniquely identify every line of text by some string (or some few strings), as with 'tex' (or just 'x') in your example: txt2mat('example.txt','BadLineString',{'tex'}) If that is not possible, you could read in all lines and then remove all NaN-only rows: A = txt2mat('example.txt',0,'ReadMode','line') A = A(any(isfinite(A),2),:) If things are more complex, you may also contact me via the 'Contact Author' link. Good luck!
02 Feb 2010	Convert TDMS (v2) Import a TDMS v2 file as a matlab object (ob). Author: Grant Lohsen	I did not test convertTDMS.m extensively, but I'll give it 5 stars as it worked with my files without any problem. Thanks, Grant!

12 Jan 2012	txt2mat fast and versatile ascii data import capable of handling large text files Author: Andres	Ramaker, Henk-Jan	Superb file! Really great! The speed and flexibility is impressive. However, i'm experiencing some troubles. When I read this txt file: Symbol,Date XXH00,09/221999 it works great! But, when I read this txt file: Symbol,Date ESH00,09/221999 txt2mat cannot read any lines. I discovered, when the 2nd line starts with an 'E' or 'N', txt2mat somehow cannot match the format. Is there a way around this or to fix this problem?
15 Nov 2011	txt2mat fast and versatile ascii data import capable of handling large text files Author: Andres	Thomas	I wasted 3 hours searching for a solution to my problem before I stumbled upon this beauty! Thanks so much for all the effort you put into this. Good explanation and examples to get you started. Part of my permanent function collection..

11 Dec 2011	optimize optimize (non)linear (in)equality constrained functions with FMINSEARCH	Shmuel	nice, but change line 12 in the testoptimize to : clc, rosen = @(x) (1-x(1))^2 + 105(x(2)-x(1)^2)^2 -6000sinc(x(2)^2+x(1)^2); % adding local minima. and you get a local minimume solver as fminsearch is.	4
02 Dec 2011	PeakFinder Quickly finds local maxima (peaks) or minima (valleys) in a noisy signal.	Diana	Hi, I find this routine very good and useful. However, for my problem I would need the start-end information about each peak so I could select just the peaks and work with them, How can I get this information? Thanks in advance	5
