conj Complex conjugate

## Syntax

    [y] = conj(x)

## Arguments

x,y

  Matrices of real or complex numbers (full or sparse storage). Matrices of polynomials or rationals, with real or complex coefficients.

## Description

`conj(x)` components are the complex conjugate of `x` components.

## Examples

    x = [1+%i, -%i; %i, 2*%i];
    conj(x)
    x'-conj(x)  //x'  is conjugate transpose

    // With polynomials:
    x = [%z-%i 2*%i %i*%z^2-1]
    conj(x)

    // With rationals:
    A = [ %z/(1-%z)  (1-%z)/%z^2]
    B = A(1,[2 1])
    C = A + %i*B
    conj(C)
    B,imag(conj(C))
