multiple arrays to one text file

header1= 'Name file';
header2='Median frequencies of MVCs';
outputFile1 = fopen(fullfile(mydir1,'Results.txt'),'w');
fprintf(outputFile1, '%-32s%32s\n', 'Name file', 'Median frequencies of MVCs ' ) 
fprintf(outputFile1,'%-32s%32s\n', filename, Medianfreq)

filename is a structure (3x1) and Medianfreq is a number array. The Medianfreq is correctly exported to a txt file but I can not seem to get the structure in there. Also, i want these two variable next to each other like this:

filename1 30 filename2 31 filename3 87

And this for all of my filenames and median frequencies. How can I do this? Please help!
