Try this:
result = 1
for k = 1 : n
result = result * (x - k);
end

You can do this:
result = 1
for k = 1 : length(z)
result = result * (x - z(k));
end
The simplest solution, without any loops:
prod(x-z)

I do not understand why you are raising to the z'th power ??

@Walter Roberson: experimenting around, and not paying enough attention to the copy-and-paste :(
