A=[1,0,-i;0,0,0;-i,0,1] B=[1,0,-1;0,0,0;-1,0,-1]。如何用matlab把B算符在A算符下展开
直接矩阵相乘就行:
A=[1,0,-1i;0,0,0;-1i,0,1];
B=[1,0,-1;0,0,0;-1,0,-1];
A*B
结果:
1.000000000000000 + 1.000000000000000i 0.000000000000000 + 0.000000000000000i -1.000000000000000 + 1.000000000000000i
0.000000000000000 + 0.000000000000000i 0.000000000000000 + 0.000000000000000i 0.000000000000000 + 0.000000000000000i
-1.000000000000000 - 1.000000000000000i 0.000000000000000 + 0.000000000000000i -1.000000000000000 + 1.000000000000000i
