Answer 1

The comma is an issue in Matlab, could you use dots instead?

-0.229447 0.003749 0.003599

-0.056431 2.009800 1.003600

-0.229128 0.004065 0.004236

-0.228810 0.004382 0.003599

If 'data.txt' is your containing file, the following should work:

fid = fopen('data.txt');
my_data = fscanf(fid, '%f %f %f', [3 4]);
fclose(fid);

files are exported from labview in txt, are saved with commas, I think I will reach a solution exporting data from LB, dots and commas create problems as because in Europe to US the use of comma-dot in numers is different.

There is any solution to modify, in Matlab the %f number recognison with commas? dude so I hope and search:)
