Function std.numeric.dotProduct

Computes the dot product of input ranges a and b. The two ranges must have the same length. If both ranges define length, the check is done once; otherwise, it is done at each iteration.

CommonType!(ElementType!Range1,ElementType!Range2) dotProduct(Range1, Range2) (
  Range1 a,
  Range2 b
if (isInputRange!Range1 && isInputRange!Range2 && !(isArray!Range1 && isArray!Range2));

CommonType!(F1,F2) dotProduct(F1, F2) (
  in F1[] avector,
  in F2[] bvector

F dotProduct(F, uint N) (
  scope const ref F[N] a,
  scope const ref F[N] b
if (N <= 16);
