How to save a matrix output to a text file that located in different folder?

34 views (last 30 days)
Hello All,
I want to save a matrix output (My_matrix ) to a text file (scaled_1.txt) that located in different folder than the script (.m file).
I have tried
fid = fopen('F:\output\scale\scaled_1.txt', 'w');
fprintf(fid, '%s\n', ' My_matrix ');
fclose(fid)
This will only print the text (My_matrix ) and not the content of the matrix.
I appreciate your suggestions in advance
Thanks

filename = 'F:\output\scale\scaled_1.txt';
arrayname = 'My_matrix';
fid = fopen(filename, 'w');
fprintf(fid, ' %s \n', arrayname);
fclose(fid)
save(filename, arrayname, '-ascii', '-double', '-append');

Thank you Walter for the great suggestion as usual. BUT!! The code you suggested was able to write the matrix to the specified text file but it also writes the matrix name (My_matrix) to the text file at the beginning. Do you have any further adjustment to prevent printing the matrix name to the text file and only keep matrix content.
Thank you,

I have removed this line fprintf(fid, ' %s \n', arrayname); which responsible for the typing the string, and it works great Thanks again
