maple 计算矩阵的秩 等
> A:=matrix([[1,-3,4,5],[2,-2,7,9],[3,3,9,12]]);
[1 -3 4 5]
[ ]
A := [2 -2 7 9]
[ ]
[3 3 9 12]
> det (A);
det(A)
> adj(A);
adj(A)
> rank(A);
rank(A)
> A:=matrix([[1,-3,4,5],[2,-2,7,9],[3,3,9,12]]);
[1 -3 4 5]
[ ]
A := [2 -2 7 9]
[ ]
[3 3 9 12]
> det (A);
det(A)
> adj(A);
adj(A)
> rank(A);
rank(A)
你的矩阵不是方阵,删掉一列后的命令：>with(linalg)：>A := Matrix([[1, -3, 5], [2, -2, 9], [3, 3, 12]]);>det(A)0> adj(A);Matrix(3, 3, {(1, 1) = -51, (1, 2) = 51, (1, 3) = -17, (2, 1) = 3, (2, 2) = -3, (2, 3) = 1, (3, 1) = 12, (3, 2) = -12, (3, 3) = 4})>rank(A)2
