22 Dec 2010 matlab2tikz A script to convert MATLAB/Octave into TikZ figures for easy and consistent inclusion into LaTeX. Author: Nico Schlömer

Hi everybody!

first of all: Thank you Mr. Schlömer for matlab2tikz. This is a great piece of a software.

Unfortunately, I have had the following problems when using version 0.0.7 in Matlab 2009b on a 64bit Linux system:
1. Labels and titles could not be written by sprintf, since it where cells.
2. Barplots did not work, since there was a typo (e.g. m2t was missing)
3. I need to plot time signals with a very small difference. That is why the precision in the pgfplots coordinates were not sufficient.
4. When plotting data series with several thousand data points, it took minutes to write the file (due to strcat and a lopp for i=1:length(xData)

I have made changes to the file which takes care of this issues:
1. e.g:

if iscell(title)
title = title{:};
end

2. for me replacing
barplotTotalNumber = barplotTotalNumber + 1;
with
m2t.barplotTotalNumber = m2t.barplotTotalNumber + 1;
helped
3. I added an option for the script where you can add a precision of the format string that is used when writing to the pgf file
4. I replaced the for loop with a repmat construction that reduced computation time a lot.

If anybody has encounters the same issues, I can send this file to Mr. Schlömer maybe (if he likes to add the changes). Or is there a better way to take care of that?

Kind regards

Alexander

Nice tool to play with data, once the GUI is understood
