I have a function. For my class, we have to put result output at the bottom of our code. However, functions have to be at the bottom. Is there a way I can use fprintf statements under the function?
%% Section 2: Processing
function y=vorder(x)
N=length(x);
y=x;
for i=2:N-1
if y(i-1)>y(i)
tmp=y(i);
y(i-1)=y(i);
y(i)=tp;
end
end
for i=N-1:2
if y(i)<y(i-1)
tm=y(i);
y(i)=y(i-2);
y(i-1)=tmp;
end
end
end
%% Section 3: Result Output ERRORS HERE
fprintf('Input and output\n');
fprintf('%d ',x); fprintf('\n');
fprintf('%d ',y); fprintf('\n');

You can use another function that includes frprintf statements.
Also, the order of functions are nor important. It is not necessary to use fprintf after the function.

Yes.
Try something like this:
x = ...;
y=vorder(x); % Call Function
fprintf('Input and output\n');
fprintf('%d ',x); fprintf('\n');
fprintf('%d ',y); fprintf('\n');
function y=vorder(x)
. . .
end
You need to call the function to get the output from it. Then write the output. The function itself is at the end of the script file.
I did not run this, so I will leave it to you to experiment with it.

Let x be your vector.
fmt = [repmat('%g, ', 1, numel(x)-1), '\n'] ;
fprintf(fmt, x)
