makeLCPFromCaltech.m

function lcp = makeLCPFromCaltech(calib_resultsPn)
% Creates the lens calibration profile (lcp) for a camera, based on
%   "Calib_Results.mat" generated from the Caltech Calibration toolbox.
%
% Input:
%   calib_resultsPn = full directory path where "Calib_Results.mat" are saved
%
% Output:
%   lcp = lens calibration profile (struct)
%
% Usage: lcp = makeLCPFromCaltech(calib_resultsPn)
