You want to multiply s*v, so perform that multiplication, but without using the * operator? May I ask why you want to do such a silly thing, instead of just doing s*v?
As long as one of them is a scalar, then conv will suffice.
conv(s,v)
It will be slower, less efficient. It will serve absolutely no purpose.
(See the comments in case I was wrong in interpreting the ambiguous question.)

for i=1:4
v=exp(sum(log(s)));
end

You may be right here. the request may be to write v=prod(s), without use of prod, instead of forming the product s*v.
