HI. I want to compute dot product of two vectors stored as lists a and b.a and b are of the same length.
one simple way is sum(a[i]*b[i] for i in range(len(a))) another simple way is ans=0.0 for i in range(len(a)): ans=ans+a[i]*b[i] But is there any other way which is faster than any of the above. (By the way profiling them i found that the second is faster by about 30%.) rahul -- http://mail.python.org/mailman/listinfo/python-list
