Hi Matlabers :D I have another question, I have a Txt file that is full of numbers and text, which are not created based on an easy rule. So i need Matlab to read the file, and extract some parts of it and some numbers related to this words, what shall i do? here is a part of the text, and i need Matlab to find (OnEventReached : 16, time = 4,03965837112068 ) in this text.

The following set of code should work (or give you an idea of one way of doing it):
% read from the text file into a cell array
s = textread('myfile.txt','%s');
% flatten from a cell array to a string
s = [s{:}];
% find out the index for the word "OnEventReached"
pos = (strfind(s,'OnEventReached'));
% extract from the string from OnEventReached to the end
% assuming it just happens once)
s = s(1,pos:end);
% dissect the string with textscan (assuming we are always
% looking for a
% string witht a similar format
% "OnEventReached:NUMBER,time=NUMBER,NUMBER"
result = textscan(s,'%[^:] %*c %f %*c %[time] %*c %f %*c %f',1)
