Question

matlab help, please
I am learning matlab by myself. I got trouble when creating fibonaccing sequence.

the output shows 11235813..... in a whole thing like this. I don't know how to separate them like
1 1 2 3 5 8 13 21.....

Answer 1

Here is the code I used
fprintf('The Fibonacci sequence to %d terms is \n',N)
fprintf('%g',fib)
fprintf('/n')

Answer 2

end each line with a \n (not /n)
fprintf('%g\n',fib)
will do the trick.
For simple output, you can also use disp();
A crude code would be:
a=0;
b=1;
disp(a);
disp(b);
for i=1:6
c=a+b;
disp(c);
a=b;
b=c;
end;
which gives the output of:
0
1
1
2
3
5
8
13

Answer 3

I wonder why do we have to use fprintf while we can work on it directly?

Answer 4

Oh, wait, if you want to print them all on one single line, then you just have to put an extra space after the %g
fprintf('The Fibonacci sequence to %d terms is \n',N)
fprintf('%g ',fib)
fprintf('/n')
or separate with a semi-colon + a space (or any other character(s) by doing:
fprintf('The Fibonacci sequence to %d terms is \n',N)
fprintf('%g; ',fib)
fprintf('/n')

Answer 5

oh, got you. Thanks a lot

Answer 6

fprintf gives you many formatting options, control the number of decimal places, or spacing, or carriage returns, different kinds of numeric or string outputs, etc. It's fascinating! :)

Answer 7

Yes, it is. thanks again :)
