I have to matrices x=[1;2;3] and U=[1 2 3; 4 5 6; 7 8 9].
I want to generate a .txt file of the name "output.txt" which would contain the following:
"
This is the output
x
1
2
3
U
1 2 3
4 5 6
7 8 9
"
How to do it?

A slightly unusual way but it works
x=[1;2;3];
U=[1 2 3; 4 5 6; 7 8 9];
f = fopen('data.txt', 'w');
fprintf(f, 'This is the output\n');
fprintf(f, 'x\n');
writematrix(x, 'data.txt', 'WriteMode', 'append');
fseek(f, 0, 1);
fprintf(f, 'U\n');
writematrix(U, 'data.txt', 'WriteMode', 'append');
fclose(f);

Not possible using writematrix, but you can use fprintf()
x=[1;2;3];
U=[1 2 3; 4 5 6; 7 8 9];
f = fopen('data.txt', 'w');
fprintf(f, 'This is the output\n');
fprintf(f, 'x\n');
fprintf(f, [repmat('%.2f', 1, size(x,2)) '\n'], x);
fprintf(f, 'U\n');
fprintf(f, [repmat('%.2f,', 1, size(U,2)) '\n'], U);
fclose(f);
