Ningyi2009 Posted September 13, 2019 Share Posted September 13, 2019 Hi, evevyone I met one question, when I read one book about linear algebra.There is one matrix A which is m by n matrix, and it has pseudoinverse A+, how can I prove the A++ = A? Could some help me to give the detailed proofs? Many thanks in advanced. Best regards, Ning Link to comment Share on other sites More sharing options...
