In this article, we will discuss how to multiply two matrices containing complex numbers using NumPy but first, let’s know what is a complex number. A Complex Number is any number that can be represented in the form of x+yj where x is the real part and y is the imaginary part. Multiplication of two complex numbers can be done using the below formula –
NumPy provides the vdot() method that returns the dot product of vectors a and b. This function handles complex numbers differently than dot(a, b).
Printing First matrix: [2.+3.j 4.+5.j] Printing Second matrix: [8.+7.j 5.+6.j] Product of first and second matrices are: (87-11j)
Example 2: Now suppose we have 2D matrix:
Printing First matrix: [[2.+3.j 4.+5.j] [4.+5.j 6.+7.j]] Printing Second matrix: [[8. +7.j 5. +6.j] [9.+10.j 1. +2.j]] Product of first and second matrices are: (193-11j)
