write a matrix to a .txt file

Hello;

I am trying to write the data of two column vectors "G" and "O" into two separate .txt files named "inputs.txt" and "outputs.txt" respectively. However I am unable to do so. Both column vectors are of length 994*1. I open the .txt files but they appear empty.

Do I need to create the .txt files "inputs" and "outputs" in the same directory or will MATLAB create them automatically? The files should be updated with new data of "G" and "O" each time I run the program with the existing file data being erased.

Any help in this query will be highly appreciated.

Thanks

feild1=fopen('inputs.txt','w');
fprintf(fileid1,'%d \r\n',G);
type inputs.txt
fclose(fileid1);
fileid2=fopen('outputs.txt','w');
fprintf(fileid2,'%d \r\n',O);
type outputs.txt
fclose(fileid2);

dlmwrite('inputs.txt',G) %easy and efficient, assuming datas are only double

dlmwrite('outputs.txt',O)

Did you try my answer? Say if something isn’t clear

Thanks, it works perfectly.

can you tell me when I open the file using the default windows notepad the files are unreadable and without spaces. However when I open them using Notepad++ the data appears to be readable.
