Abstract :
The column-unitary matrix whose range space is closest, in the Frobenius norm metric, to the range of a given matrix and whose columns belong to the null space of another specified matrix is obtained. An application of the matrix optimization result derived herein to constrained beamformer design in array signal processing is briefly described.<>
