CONJ function

Description

CONJ(A) returns the complex conjugate of a complex number. The complex conjugate of the complex number a + bi  is a − bi.

The argument A can be a real number, a complex number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the CONJ function applied to all elements.

Note that

$$ (a+bi)\times (a-bi) = abs(a+bi)^2 $$

Example

CONJ(2+3i) returns 2-3i
