In mathematics, an inner product space (or, rarely, a Hausdorff pre-Hilbert space ) is a real vector space or a complex vector space with an operation called an inner product. The inner product of two vectors in the space is a scalar, often denoted with angle brackets such as in . Inner products allow formal definitions of intuitive geometric notions, such as lengths, angles, and orthogonality (zero inner produ… WebApr 29, 2014 · It is a little tricky, but your inner products of vectors made up of -1s and 1s can be converted to XOR-ing and counting non-zero items of vectors made up of 0s and 1s.And of course the best container for a 32 item vector of 0s and 1s is an uint32.The following code does the same as what you propose, but running it vectorized in chunks …
