# Read data from .dat file

Hey,
I am trying to read some data from a .dat file, by using the textscan function. The Problem is, that MATLAB outputs me a cell array where the cells contain the whole column of my data and I am not able to adress each element individually, which I will need for further evaluation. Sb knows what I am missing here?

datacell = textscan(fid, '%u %u %f64 %f64 %f64','HeaderLines', 1);

You've given textscan directions to read 5 columns where the first two are %u (integers) and the next three are %f64 (doubles). Considering that you are specifying data types per column, Matlab has to give you each column separately. It's standard to put the columns together into a cell array.
You can access row 5 of column 1 by indexing twice as follows:
datacell{1}(5)
ans =
5
Does this solve your problem? What else are you trying to do with the data?

Thanks was exactly what I was looking for, and didn't expect this cell array + 'regular array' syntax.
I guess I am just going to make some graphs, standard deviation and maybe look for correlation. Nothing fancy :)
Thanks again and a merry Christmas you all!
