I would like to build an array of unspecified length by using the following input method:

input('Input a value for n greater than or equal to 1. If complete enter 0 ');

The length of the array is to specified and the array completed by entering zero. Can this be done?

one of the very many solutions
- here, we use a ...reasonable... preallocation scheme...

n=1024; % <- use your prealloc number...
v=nan(1,n,'double');
for i=1:n
vt=input('enter a number -or- end with a 0 < ');
if vt==0
break;
end
v(i)=vt;
end
v=v(1:i-1);
disp(v);
