POHow can I read lines with different number of data entries from text file into array in Matlab?
text
Body
copied!<p>I have a text file containing message and timestamps:</p> <pre><code> {193220,message,ucontroller9,controller1,lowalarm,success}, {193220,message,controller1,changer,{change,down},success}, {193220,controlaction,tapchange_down,{oldsetting,0.975},{newsetting,0.95}}, {193220,modelupdate_start,changeup,changer,193220}, {14430,modelupdate_complete}, {278480,message,ucontroller6,controller1,highalarm,success}, {278480,message,controller1,changer,{change,up},success}, ... </code></pre> <p>I would like to read these lines into an array and re-order the array based on the first column. My approach so far has been as follows:</p> <pre><code>fid = fopen('messagestore.txt') % Open file n=1 while 1 string = fgetl(fid); % get line if ~ischar(string), break, end % break if end of file string = strrep(string,'[',''); % string = strrep(string,']',''); % string = strrep(string,'{',''); % strip out unwanted characters string = strrep(string,'}',''); % string = strrep(string,',',' '); % string = string(2:end); % remove space at start MessageArray(:,n) = textscan(string,'%f%s%s%s%s%s'); % format and save into array n=n+1; end fclose(fid) </code></pre> <p>This partially works but I am having a problem with discriminating between different message types (i.e. number of fields). I'm guessing that I could use the matlab <code>sort</code> function if I could just get the data into an array properly.</p> <p>Is there a way to do this in matlab? </p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
