Matrix theory basis (1)

1. conjugate complex

In mathematics , the complex of the conjugate complex (often referred conjugated ) are calculating the imaginary part of the variable number, thus a complex

It is the complex conjugate

Understood as the complex the complex plane , then the complex conjugate is nothing but the real axis reflection . A plurality of complex conjugate is sometimes table

2. A complex conjugate of the matrix A * is defined as [A *] ij = aij *

3. Matrix operations

Matrix multiplication is not commutative.
