o=[3,1,9];
This is an example of array. I want to multiply them each others. For example;
3x1x9 = 27
The lenght of array could be different. How can I calculate the multiplaction with for loop.

Ran in:
o = [3 1 9];
% no for loop:
p = prod(o);
disp(p);
27
% some for loop:
p = 1;
for ii = 1:numel(o)
p = p*o(ii);
end
disp(p);
27

product = prod(o)
is the short version,
product = 1.0;
for i = 1:numel(o)
product = product*o(i);
end
product
is the long version.
