Loading the communications package does not automatically load the statistics package, but qfuncinv in the comm pkg requires norminv from the statistics pkg.  Using qfuncinv after loading the comm pkg produces an error re an undefined function unless the statistics package is also loaded.

I would recommend replacing the line:

y = -norminv(x)


y = sqrt(2)*erfcinv(2*x)

in qfuncinv.m to remove the dependency.  (erfcinv is built-in)  norminv ultimately relies on erfcinv to produce a result anyway.
