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.
