I have a text file with content like this:
35.921 M, 220,000, 48.509 M, 6.349 M, 54.052 M, 806,362, 41.018 M, 4.006 M, 41.564 M, 3.46 M, 40.02 M, 100,000, 39.22 M, 900,000, 36.974 M, 30,000, 36.549 M, 455,500, 35.739 M, 230,000, 33.104 M, 2.866 M, 19.627 M, 0, 18.877 M, 750,000, 19.603 M, 4.379 M, 23.982 M, 0, 10.186 M, 250,000, 10.436 M, 0, 15.414 M, 250,500, 15.465 M, 200,000, 21.571 M, 665,000, 22.236 M, 0, 15.537 M, 250,000, 15.787 M, 0, 21.422 M, 221,004, 21.243 M, 400,000, 30.662 M, 2.375 M, 33.036 M, 0, 39.287 M, 455,000, 39.742 M, 0, 53.141 M, 6.11 M, 59.131 M, 120,000, 23.587 M, 255,000, 23.842 M, 0, 17.043 M, 255,000, 17.298 M, 0, 33.51 M, 1.25 M, 34.75 M, 10,000, 36.408 M, 15,000, 28.248 M, 8.175 M, 32.367 M, 480,000, 31.535 M, 1.312 M, 54.773 M, 2.68 M, 43.936 M, 13.517 M, 58.955 M, 2.54 M, 41.234 M, 20.262 M, 45.222 M, 15,000
That I like to fill them into a N*4 dimentional matrix like this:
35.921 M, 220,000, 48.509 M, 6.349 M
54.052 M, 806,362, 41.018 M, 4.006 M
41.564 M, 3.46 M, 40.02 M, 100,000
How can I do it on Matlab?
I have attached my file to my question.

str = fileread('store.txt');
str = strtrim(str);
C = regexp(str,'\s*,\s*','split');
[fid,msg] = fopen('store2.txt','wt');
assert(fid>=3,msg)
fprintf(fid,'%s, %s, %s, %s, %s\n', C{:});
fclose(fid);
EDIT: see the comments for further developments of this code.
