Source Code:

naca4_mpt.m,
extracts the M, P and T parameters from a NACA 4 digit code.

naca4_cambered.m,
given a point xc along the camber line, returns pairs
(xu,yu) and (xl,yl) along the upper and lower airfoil surface
of a NACA cambered 4digit airfoil.

naca4_symmetric.m,
given a point x, returns the value y(x) so that (x,y(x))
lies on the upper surface of a NACA symmetric 4digit airfoil
and (x,y(x)) lies on the lower surface.

r8mat_write.m,
writes an R8MAT to a file.
