Abstract:
1. A method for nulling a cell of a complex matrix, comprising: obtaining the complex matrix as input to a processing unit; obtaining a modified Givens rotation matrix as input to the processing unit; multiplying the complex matrix with the modified Givens rotation matrix by the processing unit for the nulling of the cell of the complex matrix to provide a modified form thereof, the modified form comprising real numbers; and outputting the modified form by the processing unit; the modified Givens rotation matrix including complex numbers c*, c, −s, and s*, wherein the complex number s* is the complex conjugate of the complex number s, and wherein the complex number c* is the complex conjugate of the complex number c; and the complex numbers c and s being associated with complex numbers of the complex matrix including the cell to be nulled.
