No text appearing in my .txt file using fprintf

Hello,

I'm trying to write the following string array to a .txt file. However, no data is being written to any file.

label = 

  19×3 string array

    "3182.77"    "3211.7042"    "Syl_1" 
    "3305.49"    "3311.4764"    "Syl_2" 
    "3321.45"    "3351.382"     "Syl_3" 
    "3417.23"    "3470.1098"    "Syl_4" 
    "3494.06"    "3560.9081"    "Syl_5" 

I'm trying to write the file to a specific location, so I've included the appropriate directory in my file name:

    wavfilecd = 

    "/Users/aalonso/Documents/Birdsongs/Millibrook/Cohort1/box1_l24y109/UD/L24Y109_43320.47040589_8_8_13_4_0.txt"

I'm using the following code to export my array to a text file.

     fopen(wavfilecd,'w');
     fprintf(wavfilecd,'%s \t %s \t %s \n',label)
     fclose('all');

Right now a file is being created in the right directory, but when I open it there's nothing there. Can anyone help me populate the text file?

Best,

Ana

     fid = fopen(wavfilecd,'wt');
     %^^^^                   ^
     fprintf(fid,'%s \t %s \t %s \n',label.')
     %       ^^^                          ^^
     fclose(fid);
     %      ^^^

This is perfect, thank you so much! Was totally overlooking that I need to assign fopen to a variable!

I’ve never seen that particular syntax.

Try this:

     fid1 = fopen(wavfilecd,'w');
     fprintf(fid1,'%s \t %s \t %s \n',label')
     fclose(fid1);

Also, you need to transpose ‘label’ (as I did here) to get it to print the way you want it to.

Thank you so much! It's working perfectly now!
