matlab Matrix must be square.怎么解决
以下是我的运行程序,运行时总是出现这样的结果
Error using ==> mtimes
Inner matrix dimensions must agree.我该如何修改这个程序（我要做出H关于t的函数图像）
l1=36.15;l2=553.353;l3=400;l4=290;
t=linspace(0,2*pi,100);w=2*pi;
A=l4-l1*cos(w*t);B=-l1*sin(w*t);C=(A^2+B^2+l3^2-l4^2)/(2*l3);
sa3=2*atan((B+sqrt(A^2+B^2-C^2))/(A-C));
H=l3*sin(sa3)*2;
plot(t,H);

改成：l1=36.15;l2=553.353;l3=400;l4=290;t=linspace(0,2*pi,100);w=2*pi;A=l4-l1*cos(w*t);B=-l1*sin(w*t);C=(A.^2+B.^2+l3^2-l4^2)/(2*l3);sa3=2*atan((B+sqrt(A.^2+B.^2-C.^2))./(A-C));H=l3*sin(sa3)*2;plot(t,H); 输出：

matlab Matrix must be square.怎么解决 matlab Matrix must be square什么情况? matlab总是mpower Matrix must be square. MATLAB 画图出现Matrix must be square matlab编程中出现Matrix must be square.怎么办? Matlab中出现了Matrix must be square. matlab 基础出错,求指导 Matrix must be square matlab Error using ==> mpower Matrix must be square. matlab 出现Matrix dimensions must agree 怎么解决 matlab错误：? Error using ==> mpower Matrix must be square. 向高手 matlab 急救 Inputs must be a scalar and a square matrix. matlab画图实验时出现错误,显示：Matrix must be square
