Writing my data to a table.

This is probably a really basic fix, but I can't get my data to write to a table. What I have is a for loop that opens a .txt file, performs some functions on it, and returns the result. What I want is for the filename, and end result, to be displayed as a table and I can't seem to get it to work. Anyone know what function would work?

for fileidx = 1 : numel(files)
    mydata{fileidx} = importdata(fullfile(folder, files(fileidx).name));
    y=fft(mydata{fileidx});
    c=xcorr(xf,y);
    m=mean(abs(c));

end

What exactly do you mean by "displayed as a table"? Do you mean you want to put the information in to a table class variable and display it? Or you want to print the data to a txt file in a style that looks like a table? Or you want to print the data to a file that can be read by something like Excel and organized into a table?

I want something that looks like this:

fileidx, m

1, **

2, **

etc It doesn't need to be an excel file, it just needs to show all the data.

It would be fairly easy to print something like that into a txt file (or similar format). You could use fprintf to print the file name first and then dlmwrite for the data matrix.

fprintf(fileout,fileidx)
dlmwrite(fileout,resultsmatrix,'-append') % Default delimiter is ' ' I think.

What is fileout? I'm getting 'undefined'.

[Walter Roberson]

out_filename = 'Output.txt';

fileout = fopen(out_filename, 'wt');
fprintf(fileout, 'fileidx, m\n');
fclose(fileout);

dlmwrite(out_filename, resultsmatrix,'-append');   %default delimiter is comma

[George Scott]

Still getting undefined, what exactly do you mean 'out_filename'?

[Bob Thompson]

out_filename or fileout are variable defined in MATLAB by the script to contain the string of characters of the name of the file you would like to output the results into. It is the same basic concept as files.name except that files.name is a structure class variable and calls your input files, not your output files.
