Hi
I have a text file which has data of the following format:
17,1413736800061,4,2
17,1413736800153,12,0
17,1413736800239,6,2
17,1413736800324,5,1
17,1413736800410,6,1
17,1413736800496,6,1
.....
.....
Now, when I read in the file with M = csvread(fileName); and then I print the matrix M in Matlab I get values like the following (the values do not correspond to the ones above).
0.000000000017000 1.413737868957000 0.000000000003000 0

0.000000000017000 1.413737869634000 0.000000000004000 0
How can I get just normal vlues without a decimal point?

But it is the input data...you're ignoring the scale factor Matlab uses when display disparate values on the command window...
>> type sepp.csv
17,1413736800061,4,2
17,1413736800153,12,0
17,1413736800239,6,2
17,1413736800324,5,1
17,1413736800410,6,1
17,1413736800496,6,1
>> csvread('sepp.csv')
ans =
1.0e+12 *
0.0000 1.4137 0.0000 0.0000
0.0000 1.4137 0.0000 0
0.0000 1.4137 0.0000 0.0000
0.0000 1.4137 0.0000 0.0000
0.0000 1.4137 0.0000 0.0000
0.0000 1.4137 0.0000 0.0000
>> [ans(:,1) ans(:,3)]
ans =
17 4
17 12
17 6
17 5
17 6
17 6
>>
NB: the 1.0e+12 * in the beginning of the array after reading the file; it's significant.
To see the values are really there, then displayed the first and third columns so the scaling is unity.

Thank you very much. It's my fault, I didn't see the scaling factor because I have such an enormous amount of data.
