Hello All, I am working on a script where I am requesting user to select file and provide inputs. Here is the code I am using:

[FileName2,PathName2] = uigetfile({'*.txt';'*.csv';'*.*'},'Select the text file that contains inputs parameters');
if isempty(FileName2)
    errordlg('No file was selected that contains the data is required format.Hence the calculation was aborted.');
    return
end
fid2 = fopen(fullfile(PathName2,FileName2));
if fid2 == -1
    errordlg('The file selected for the inputs could not be read so the calculation was aborted.');
    return
end
in_data = textscan(fid2,'%f%s');
fclose(fid2);

The error I am facing now is the data type I am reading.

Here is the sample "input.txt":

-9.11 #1st input
23 #2nd input
#3rd input
   #4th input
   #5th input

Now the problem is , the input file will always have 1st column as numbers which I am interested in. and I just want to ignore the next columns. But with my above code, matlab reads only 1st number. If I remove all comments, it reads all numbers. So i want help to ignore all other columns and just read 1st column.
