Hi;

I have multiple text files with this format:

yes 1 1 1 1 0 0 1 0

yes 0 0 1 1 0 1 0 1

yes 0 1 1 0 1 0 1 1

yes 0 1 1 1 1 1 0 1

- the number of rows are different from file to file.

- I don't know the number of binary in each row(But i believe all rows have the same number)

**I need to save only the binary

I have tried this code

for i=1:1

 for j=1:8
    fid = fopen(strcat('C:\Experiment\Test',num2str(i),'_',num2str(j),'.txt'), 'r');
    firstcell = textscan(fid, '%d', 1);
    restcell = textscan(fid, '%*s%s', 'CollectOutput', 1);
    fclose(fid);
    firstCell = firstcell{1};
    rest = restcell{1};
    filename=strcat('Result', num2str(i),'_',num2str(j),'.mat');
    save(filename,'rest');%,'delimiter',' ' );
 end
end
The problem here is:
it saves the entire binary numbers into single column.
I need to have the file output looks like this:
1 1 1 1 0 0 1 0
0 0 1 1 0 1 0 1
0 1 1 0 1 0 1 1

*/ many thanks to Walter Roberson , for his inspiration for the above code

Maybe there's a more clever way but nothing I can get to work at the moment...

textscan(l, ['%*s' repmat('%d',1,8)]', 'CollectOutput', 1)

You need to read a line ( fgetl is a help here) and count the number of digits if you don't know a priori to give textscan some help in the parsing.

In passing, another advantage in Fortran FORMAT, one could use recursion to skip the one string then repeat the %d w/o the explicit number of fields by use of parentheses. AFAIK there's no way to do that in C.
