- 试求一个正交相似变换矩阵,将下列实对称矩阵化为对角矩阵 [tex=6.143x3.5]075gCzZzsMRb6HYXYk9X9zQqYJzbaed4lVR97kGPEgvaxagvjk3Cgqe327d5yPrIDXRdgeKcg1hPBdODhJlpB6BFNmg9GQDNGPRBlXkZe1k=[/tex]
- 【计算题】5 ×8= 6×4= 7×7= 9×5= 2×3= 9 ×2= 8×9= 7×8= 5×5= 4×3= 5+8= 6 ×6= 3×7= 4×8= 9×3= 1 ×2= 9×9= 6×8= 8×0= 4×7=
- 将矩阵a=[1 2 3;4 5 6;7 8 9]改变成 b=[3 6 9;2 5 8;1 4 7]的命令是( )。
- >>>x= [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9]>>>print(x.sort()) 语句运行结果正确的是( )。 A: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10] B: [10, 6, 0, 1, 7, 4, 3, 2, 8, 5, 9] C: [10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0] D: ['2', '4', '0', '6', '10', '7', '8', '3', '9', '1', '5']
- set1 = {x for x in range(10)} print(set1) 以上代码的运行结果为？ A: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} B: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,10} C: {1, 2, 3, 4, 5, 6, 7, 8, 9} D: {1, 2, 3, 4, 5, 6, 7, 8, 9,10}
