I have a .dat mesh file which looks something like this
v 0 1 2 3
v 2 4 5
Any idea how I can read the file in matlab and find the number of occurrences of a particular string and also the number of integers in a particular row?
No products are associated with this question.
Just read it in line by line with fgetl(). Then use strfind() on each line to see if some sequence of numbers you're interested in exists in the string.
fid = fopen('sandeep data.dat);
tline = fgetl(fid); while ischar(tline) disp(tline) tline = fgetl(fid); if strfind(s, '2 4 5') > 0 message = 'Found it'; uiwait(msgbox(message)); end
