help fplot:

N is the minimum number of points to use.  When N is specified, maximum
stepsize will be 'XHI - XLO / N'.

Does 'XHI - XLO / N' refer to '(XHI - XLO) / N' rather than 'XHI - (XLO / N)'
?


help surfnorm:

If output arguments are requested then the components of the normal
vectors are returned in NX, NY, and NZ and no plot is made.  The
normal vectors are unnormalized (magnitude != 1).  To normalize,
use
     mag = sqrt (nx.^2 + ny.^2 + nz.^2);
     nx ./= len;  ny ./= len;  nz ./= len;

In the above example code, do 'len' and 'mag' refer to the same variable ?
