Web3 sep. 2024 · Scalar multiplication or dot product with numpy.dot. Scalar multiplication is a simple form of matrix multiplication. A scalar is just a number, like 1, 2, or 3.In scalar multiplication, we multiply a scalar by a matrix.Each element in the matrix is multiplied by the scalar, which makes the output the same shape as the original matrix. WebComplex number. A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i2 = −1. In mathematics, a complex number is an element of a number system ...
