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

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.

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).

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!

Brilliant work - saved me a day. Much better than Matlab itself.
