MATLAB: String Manipulation and File Input/Output -

ok have data file similar 1 containing names , weights of people:

darby george          166.2 helen dee            143.5 giovanni lupa    192.4 cat donovan       215.1 

im supposed read script strings 1 line @ time, save weight vector, , print each person's name in form 'last,first' followed weight:

george, darby’s weight 166.20 lbs. dee, helen’s weight 143.50 lbs. lupa, giovanni’s weight 192.40 lbs. donovan, cat’s weight 215.10 lbs. 

this code:

fid = fopen('patwts.dat'); if fid == -1     disp('file open not successful') else     while feof(fid) == 0     % read 1 line string variable     aline = fgetl(fid);     %save vector , fprintf here     strtok(aline,' ')=[first last num];     fprintf('%s %s %3.2f',last,first,num)     mat=['%3.2f %3.2f %3.2f %3.2f %3.2f %3.2f 3.2f %3.2f %3.2f %3.2f']     end     closeresult = fclose(fid);     if closeresult == 0         disp('file close successful')     else         disp('file close not successful')     end end fprinf('the average weight $sum(%3.2f)/2 lbs', num) 

i'm having problems strtok function.

i don't know how format string read 'last, first' weight.

[token, remain] = strtok(aline,' ') return first token "darby" , remain of line. don't think looking for. suggest use strsplit(aline, ' '), return cell containing tokens , need each "first, last, num" doing loop (for example)
