How can I write strings and matrices to a .txt file in MATLAB?

Question

I need to write data to a .txt file in MATLAB. I know how to write strings (fprintf) or matrices (dlmwrite), but I need something that can do

Answer 1

You don't need the empty matrix call. Try this code:

str = 'This is the matrix: ' ;
mat1 = [23 46 ; 56 67] ;
fName = 'output.txt';
fid = fopen('output.txt','w');
if fid>=0
    fprintf(fid, '%s\n', str)
    fclose(fid)
end
dlmwrite(fName, mat1, '-append', 'newline', 'pc', 'delimiter','\t');
