Parameters —

1. vector_a: [array_like], if a is complex, its complex conjugate is used to calculate the point product.
2. vector_b: [array_like], if b is complex, its complex conjugate is used to compute the dot product.

Return — point Product of vectors a and b.

Code 1:

Output:

 Dot Product: (23-2j) 

How does Code1 work?
vector_a = 2 + 3j
vector_b = 4 + 5j

According to the method, take the conjugation of vector_a, i.e. 2 — 3j

now product point = 2 (4 — 5j) + 3j (4 — 5j)
= 8 — 10j + 12j + 15
= 23 — 2j

Code 2:

Output:

 Dot Product: 55 Dot Product: 55
