trace(5*eye(6))=
举一反三
- 运行下面的程序：>;>; a=eye(5);>;>; for n=a(2:end,:)……循环次数为______. A: 4 B: 5 C: 3 D: 6
- 有以下语句，for的循环次数是a=eye(6)for n=a(3:end,:)nend A: 3 B: 4 C: 5 D: 6
- speye(5)与sparse(eye(5))的功能一样。
- The function full(speye(5)) has the same function as the function eye(5).
- The function speye(5) has the same function as the function sparse(eye (5)).
