[Undescribed Horrific Abuse, One Victim & Survivor of Many]

I'm thinking it could make sense to just do it complex-domain, and let
the matrices be mutated to real after the fact.

I'll look at what's needed for this one.

hmmm ... i could create the complex frequencies from the real ones
pretty easily. but why then would i make real-only frequencies?

given the real-only frequencies presently passed, i could make them
complex by negative the last one, and adding a negative copy of [1:-1]
to the end.

the frequencies are the columns, so that would make the columns higher.
and, i could perform the same operation to the columns, to test it.

ok i made a 28x28 matrix from the 15x28 with
np.concatenate([irft15[:-1], -irft15[-1:], -irft15[-2:0:-1]], axis=0)
. what i forgot is i then need to do that same thing to the frequency
data.

... i think? uhhh ... sure?

well i think it didn't work, but again it's a completely closed space
so troubleshootable
