Summary: | Several new expressions are proved for the
m
-weak group inverse. An effective algorithm for computing
m
-weak group inverse in terms of the QR decomposition is proposed. Applying the
m
-weak group inverse, we present the uniquely determined solution to the restricted minimization problem in the Frobenius norm:
