On 09/30/2009 05:32 AM, s4y asked why the code:
[fid] = fopen("test2.txt", "r", "native");
[m, count] = fscanf(fid, "%f:%f:%f %f %f %f %f %f %f",[2,9]);
fclose(fid);
incorrectly chops up the following data file
16:09:06 32.41 32.63 36.43 36.63 36.65 34.56
16:09:13 32.39 35.63 46.43 66.83 26.65 34.56
The best way to think about it is that fscanf() reads a stream of data
into a single column, which can then be reshaped. You ask for a [2,9]
form, which chops 2-row-long columnar pieces and assembles them into 9
columns. If you do
[m, count] = fscanf(fid, "%f:%f:%f %f %f %f %f %f %f",[9,2]);
and transpose ( m' ) you will get your desired result.
