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);
