function A = FSA(h, m)
% FSA height, mass
% FSA(H, M) computes the frontal body surface area in
% square meters of a person, given her height H in
% centimeters and mass M in kilograms. To this end,
% we are making use of the Mosteller formula, which
% computes the entire body surface area, 2/5 of
% which we will presume to be frontal surface area.
error(nargchk(2, 2, nargin));
A = (2 / 5) * sqrt((h * m) / 3600);
