I have a text file. It is my experimental data in three columns. The file contain results of 10 or more experiments. The data look like this:
#"+ABC Scan/Experiment1 with 12V...
#points Xvalues Yvalues
1 100.00 3359.33
2 100.00 5584.55
3 100.00 1215.56
.........
.........
257930 1222.22 18955.55
#"+ABC Scan/Experiment2 with 14V...
#points Xvalues Yvalues
1 100.00 3359.33
2 100.00 5584.55
3 100.00 1215.56
.........
.........
257930 1222.22 18955.55
....
Like this Experiment n with V Volts.... .. This is in a single .txt file. How can I split each experiment into separate txt files and save in the order of voltages or numbered successively?

Have you tried reading the file with textread, and then saving to a new file line-by-line till you hit a '#'? You can check for a '#' using strfind.

Well if you know your data has exactly the same number of points per experiment or you can obtain how many points there are per experiment, you can use textscan().
data = textscan(fileID,formatspec,N,'headerlines',2);
Where N is the number of lines you're reading in and the field 'headerlines' skips how many lines (the header) before starting to read data.
