在命令窗口键入
[x,y]=solve('x^2+y^2=1','x*y=2')
结果如下
x =
((15^(1/2)*i)/2 + 1/2)^(1/2)/2 - ((15^(1/2)*i)/2 + 1/2)^(3/2)/2
((15^(1/2)*i)/2 + 1/2)^(3/2)/2 - ((15^(1/2)*i)/2 + 1/2)^(1/2)/2
(1/2 - (15^(1/2)*i)/2)^(1/2)/2 - (1/2 - (15^(1/2)*i)/2)^(3/2)/2
(1/2 - (15^(1/2)*i)/2)^(3/2)/2 - (1/2 - (15^(1/2)*i)/2)^(1/2)/2
y =
((15^(1/2)*i)/2 + 1/2)^(1/2)
-(1/2*15^(1/2)*i + 1/2)^(1/2)
(1/2 - (15^(1/2)*i)/2)^(1/2)
-(1/2 - 1/2*15^(1/2)*i)^(1/2)
