Dot or scalar product of vectors
WebNov 15, 2024 · The method that calulates the scalar product is supposed to take a Vector q and then calculate the scalar product of the current vector with the Vector q, so basically if "p" was my current Vector, then p.scalarproduct (q) is supposed to calculate the scalar product of p and q. So far, this is my unfinished code: public class Vector { private ... WebDot product of two arrays. Specifically, If both a and b are 1-D arrays, it is inner product of vectors (without complex conjugation). If both a and b are 2-D arrays, it is matrix multiplication, but using matmul or a @ b is preferred. If either a or b is 0-D (scalar), it is equivalent to multiply and using numpy.multiply(a, b) or a * b is ...
