function setProfile(s, name, comp, p)
% SETPROFILE - Specify a profile for one component.
%
% name -- domain name
% comp -- component number
% zr -- array of relative positions (0.0 to 1.0)
% v -- array of values
%
% The solution vector values for this component will be linearly
% interpolated from the discrete function defined by v vs. zr.
% Note that zr = 0.0 corresponds to the leftmost grid point in
% the specified domain, and zr = 1.0 corresponds to the rightmost
% grid point. This method can be called at any time, but is
% usually used to set the initial guess for the solution.
%
% Example:
%
% zr = [0 0.1 0.2 0.4 0.8 1];
% v = [500 650 700 730 800 900];
% setProfile(1, 2, zr, v);
