Rot3Dy2vect.m added
CreateCamera.m and getData.m done
calc_Ci moved to a single file and it uses a cam argument;
getData.m and CreateCamera.m are used in the main functions
calc_Ci.m calculates the inverse of the resulting covariance matrix,
so it can handle a cell containing camera structs;
calc_measure() function is deleted, simplified
rename calc_Ci() to calc_Ciw()
Some refactoring, better organized code
getData.m: image width and height added
main9.m: first calculations and plots for the distortion theory
