MATLB - how to show REAL numbers only

  1. Dec 29, 2011 #1
    I'm trying to use the MATLAB symbolic toolkit, but the "conj" term keeps annoying me. Here's an example:

    >>syms l d
    >>A=[l d ; d*l -l*l*d]
    ans =

    [ conj(l), conj(d)*conj(l)]
    [ conj(d), -conj(d)*conj(l)^2]

    How do I tell MATLAB I'm only interested in real numbers, and get rid of the conj terms? My applications do not involve any imaginary numbers at all.
