Function std.numeric.cosineSimilarity

Computes the cosine similarity 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. If either range has all-zero elements, return 0.

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