楼上的，估计不是这个原因，我设置了另一个类似的矩阵可以生成，并未预先定义字符变量 Q:=matrix([[cos(alpha), f*j*k*sin(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [cos(alpha), f*j*k*sin(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [cos(alpha), f*j*k*sin(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0], [-sin(alpha),cos(alpha),0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,ex_2,ex_1,0,0,0,0,0,0,0,0,0,0,0]]); |
