[x,y]=solve()表达式里多了个点符号'.',去掉就可以了.即
[x,y]=solve('1351.565-14.85*13-379.25*x-1.025*y^2-27.25*y=0','222.5-2.7*13-27.75*x-0.45*y^2-2.05*x*y-0.36*13*y=0','x','y')

s=solve(1351.565-14.85*13-379.25*x-1.025*y^2-27.25*y==0,222.5-2.7*13-27.75*x-0.45*y^2-2.05*x*y-0.36*13*y==0)
s =
x: [3x1 sym]
y: [3x1 sym]
s=[s.x;s.y]报错了呃。。。Undefined function ...

全部展开

s=solve(1351.565-14.85*13-379.25*x-1.025*y^2-27.25*y==0,222.5-2.7*13-27.75*x-0.45*y^2-2.05*x*y-0.36*13*y==0)
