Set a REAL function in SAGE

Hello everyone,

I have a problem when I was trying to set my function H(t) as real.

image description

H = function('H')(t)
H.is_real()

=> False

conjugate(H)

=> \bar{H}

I wanna set my function in real space and the code stop printing \bar{H] as you seen in the screen shot.

Thanks for the help. Cheers.

A simple alternative to 'setting it to be real' is to make a substitution such as this one:

whatever.subs({conjugate(H) : H, real_part(H) : H, imag_part(H) : 0})

It depends on what kind of expressions you want to get rid of.

This appears to be unsupported in either Sage or Maxima. Implementing this seems to be no small beer.
