Hello,
I'm currently studding a bubble colapse problem with Matlab. I got a graph but I want to know how can I get a Matrix or a Table (.txt or some similar type of file) with all the data from the graph. I mean, in the left will be the velocity and in the right the time correspondent to that velocity. I apologize if someone else has already asked this question but I didn't find a similar topic.
Thanks in advance.

I will have to guess that it is a line plot. If so then,
h = findobj(gca, 'type', line);
x = get(h, 'xdata');
y = get(h, 'ydata');
After that,
fid = fopen('OutputFile.txt', 'wt');
fprintf(fid, '%g %g\n', [x(:), y(:)].' );
fclose(fid);
