The angles in degrees of the two spatially propagating signals
Compute the array response vectors of the two signals
Compute the true covariance matrix
how to add arrays
* Use of const (constant) values.
* Creation of vectors.
* Passing vectors as function arguments.
* Reading from files of unknown size (monitoring istream status).
* Repetitive structures (while and for loops).
* The increment operators (++).
* Selection ...
