Reading text file, matlab

Question

I am reading a text file \'mytext.text\' in matlab. Data file looks like:

1   -4436.6910  415.1843    -3019.7497  1,3,4,5,21,23

2   -4366.4541  1353.9975   -308         


        

Answer 1

One possibility is to read the last column as string, then convert it to numbers afterward.

fid = fopen('file.dat','r');
C = textscan(fid, '%f %f %f %f %s', ...
    'Delimiter',' ', 'MultipleDelimsAsOne',true, 'CollectOutput',true);
fclose(fid);

C = [num2cell(C{1}) cellfun(@str2num, C{2}, 'UniformOutput',false)]

The resulting cell-array:

C = 
    [1]    [-4436.7]    [415.18]    [-3019.7]    [1x6 double]
    [2]    [-4366.5]    [  1354]    [-3085.1]    [1x4 double]

with:

>> C{1,end}
ans =
     1     3     4     5    21    23
>> C{2,end}
ans =
     1     3     4    23
