This equation is done so let's go to
the next one. I'm going to write B.
B and C is going to be a lot simpler
because they are just are just discretizing
easier equations. We still have the
finite different terms but this average
there are two differences. One is a minus
sign and two, there are no products.
It's linear, so the corresponding entries
instead of half of F and half of Fpp,
should be what? That's right. All right so
let's see so this is my B equation
which depends on F and Fp
right so my fpp is going to be completely 0
So let me just let me just get rid of
the a's and b's because i don't want to
modify them in every equation i'm
just going to say ah but i already knows
we see case i'm going to get rid of the
leaves so my bfp people this equation is
going to be zero my GF p and DF i'm not
going to be 0 so my jf is going to be
the justified difference my GF is going
to be responding to the wall- a task
it's actually a lot because it's not a
vector is actually our identity matrix
off let's and / 8 us by the atl right
sir actually- so this is the vicious
this term right i have here
ok and here i have the i have the same
but
alright okay so this is the derivative
with respect to ask which was not to F
prime it also initialize it as 0 but
then I add actually subtract two of
identity / 2 so subtract divide by two
alright have to be p alright
does that look like
ok looks right to me ok my matrix we is
going to be pretty much the same now the
funny difference is instead of apps f is
operated on right and the average is
operating on PP + 10 should be BF so
that's basically our see your copy right
what is left is the boundary condition
of symbolic religious the boundary
condition is the matrix of three by
three and possibly right so here I'm
just going to directly constructed
alright our let's first initialize this
to be a 03 by three times and haha so
that's my identify the matrix let's fill
out the first Rovers the first row
should be corresponding to corresponding
to f 1 equal to 0 right
what is that copy of a political 20
going on the engines that we have right
now which one on which the footwall
right so--okay so FDA of 11 is equal to
one right i mean because physically what
the do it is in suite is equal to 14 f 1
is equal to 0 for everything else
how about these two same successful on
people in disease right for this one are
my DX of the second roll
what is to be long 0 is the first entry
of FP and that should be impact to
exactly how about the third roll and a
few times n plus 1 stripes
it's FPS and password are right at peace
and polishes the seconds which is the
last entry of the set variable that's
sometimes n plus 1 alright I've done and
I don't I don't think I even use this
