[color=FF00FF][size=3][b]diff(theta,'z')=-(epsilon0*(epsilon2+epsilon1*(sin(theta))^2)*V/d*sqrt(epsilon0*epsilon2*k11))*sqrt((C+1/((1+gama*(sin(theta))^2))/(1+k*(sin(theta))^2)));   
请问其中的积分常数怎么去定义啊？用 sym C 去定义怎么不对呢？[/b][/size][/color]





[color=0000FF][size=3]J=[cos(arf) -sin(arf);sin(arf) cos(arf)]*[cosA-i*(1/(2A))*B*sinA (1/A)*(arf)*sinA;-(1/A)*(arf)*sinA cosA+i*(1/((2*A))*B*sinA];
这两个矩阵的乘积为什么错误？？？

??? J=[cos(arf) -sin(arf);sin(arf) cos(arf)]*[cosA-i*(1/(2A))*B*sinA (1/A)*(arf)*sinA;-(1/A)*(arf)*sinA cosA+i*(1/((2*A))*B*sinA];
