Simply put, calc_cov defines whether x input is made of sensor/observation data or is a precalculated covariance matrix Note: Unlike MATLAB where input matrix x is of size MxN where N represents the number of array elements, we assume row-major formatted data where each row is assumed to be complex-valued data from a given sensor (i.e. NxM) rzxMatrix has more sensors than samples.
