I have a question if there is possibility to sort through text file in matlab. I'll post 3 pictures where it says all. I have a txt file and need to make nx3 matrix from it.
-
This is first part where I have to delete first 11 rows in txt file.
-
-
Second part where I have 3 columns of numbers I need to write in matrix
-
-
Third part where I need to delete everything down from information I need to sort.

Yes.
Please upload a sample file. We cannot test code using screenshots of a text file.

>> str = fileread('kvadrat2.txt');
>> tkn = regexp(str,'^GRID\*\s+\d+\s+(\d+,\d+)\s+(\d+,\d+)\s+\d+\s+\*\s+\d+\s+(\d+,\d+)','lineanchors','tokens');
>> tkn = vertcat(tkn{:});
>> tkn = strrep(tkn,',','.');
>> mat = str2double(tkn)
mat =
0 50.0000 0
0 50.0000 50.0000
0 0 0
0 0 50.0000
0 5.0000 0
0 10.0000 0
0 15.0000 0
0 20.0000 0
0 25.0000 0
... lots of lines here
0 20.0000 30.0000
0 25.0000 30.0000
0 30.0000 30.0000
0 30.0000 25.0000
0 30.0000 20.0000
0 25.0000 20.0000
0 25.0000 25.0000
To save the matrix in a new file use |csvwrite:
csvwrite('newfile.csv',mat)
If you really need to use a comma as the decimal radix, search this forum for "comma decimal".
