这里我们只需输入如下命令即可求出解:〔x,y〕=solve(‘9*x+8*y=10’,‘13*x+14*y=12’,‘x’,‘y’)。回车后,Matlab就求出了这个二元一次方程组的解再来求一个二元非线性方程组x^2+y^2=10 式12x+3y=0 式2这里我们只需输入如下命令即可求出解:〔x,y〕=solve(‘x^2+y^2=10’,‘2*x+3...
用solve牛顿法求方程的解，只会得出一个近似解。比如说一个一元二次方程有-1和7两个解，如果我们给x赋值0，那么显示的就是-1这个解；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...

=='，但是对于符号变量，则只能是'=='。②习惯性错误，如 2x+1、xy、sinx、e^x、ln(x) 等等，这些都是错误的，会直接报错。应该改为2*x+1 x*y sin(x) exp(x) log(x)3、方程太过复杂，solve函数算法解不出来。这种情况不会报错，会返回warning说明说找不到解或是返回隐函数。
