Or maybe not, the second part of mvnun is a heavy duty loop over all
points in the data, so there is a strong reason to keep it in fortran.
Since I don't know type details in fortran, I don't know how difficult
it would be to move the creation of the temp variables of mvnun that
includes the variable dimensions declarations into a python function.
But looking at the fortran code, I have no idea, mvndist uses the
CORREL(*) instead of rho(d*(d-1)/2)
How are temp variables with flexible dimension defined in fortran77?
(If I had to fix it, knowing as little fortran as I do, I would just
add all offending temp variables into the argument list and create
them in python. Since kde is the only user of mvnun, it shouldn't be
to difficult to change)
