A=[1,2;2,3];b=[8;13];x=inv(A)*bx=A\B 这两种方法最终都会给出方程组的解，即x1和x2分别是2和3。对于多次的方程组，MATLAB提供了符号解法。首先，定义变量，例如：syms x y 然后，求解方程组：[x,y]=solve('x^2+3*y+1=0','y^2+4*x+1=0')使用vpa(F,n)函数可以求出n...
x=-3, y=-12 2y-x=2... (1), x=1+8y\ ...(2)Substituting (2) into (1) gives 2y-(1+8y)=2∴ 2y-1-8y=2∴ -6y=3∴ y=-12Substituting y=-12 into (2) gives x=1+8* -12=-3The solution is: x=-3, y=-12Check: (1) 2(-12)-(-3)=-1+3=2(2) 1+8(-12)=1-...

如果我们给x赋值10，那么显示的就是7那个解。solve返回的解是与赋值差最小的解。如果你想得到一个方程的所有解，请使用菜单里8.方程/函数功能。一元多次方程求解，选择2.多项式方程，按照步骤输入系数abc的值，按等号直接可以切换该方程的所有解。我曾经也困惑了好久，希望可以帮到你。你好...
