ef = 1.5^2; ec = -2^2; es = -1.8^2;
k0 = 1; a = 0.63; pc = ef/ec; ps = ef/es; binit = 0.5*sqrt(ef);
kf = sqrt(ef-binit^2);
as = sqrt(binit^2-es);
ac = sqrt(binit^2-ec);
tol = 1e-12; n = 1;
while 1
kf_new = (atan(-kf/ac/pc)+atan(-kf/as/ps))/2/a;
if abs(kf_new-kf) < tol, break; end
kf = kf_new;
be = sqrt(ef - kf^2);
as = sqrt(be^2 - es); %c % edit Rik: assuming this is a typo
ac = sqrt(be^2 - ec);
n=n+1;
end
E = abs(tan(2*k0*a*kf) - kf*(pc*ac+ps*as)/(kf^2 - pc*ac*ps*as)) ;
phi = (atan(pc*ac/kf) - atan(ps*as/kf) + pi)/2;
how to find the value of be from this program

The value of be will be displayed in the Worskspace sidebar.
or use the command window, typing be shows the value of be. Or you can add disp(be) at the end of the code.
For this questions it's best to google it because it has been answered many times.

As @AndresVar implies: this is a fairly basic Matlab question. You may consider doing the Onramp tutorial (which is provided for free by Mathworks).
