以下是補充過的原題議, 還有b小題複製忘了改,是column才對 答案只有a是錯的 which of these assertions is not logically equivalent to all the others? (the matrix A is mxn) n a) the row vector in A span R m b) the column vector in A span R c) A has a pivot position in each row a是錯的,想請教以上三小題的觀念,感謝! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.160.183.186
