用matlab求解非线性方程组,x(1)-[7+x(2)^2+4*x(3)]/12=0;x(2)-[11-x(1)^2+x(3)]/10=0;x(3)-[8-x(2)^3]/10=0'
用matlab求解非线性方程组,
x(1)-[7+x(2)^2+4*x(3)]/12=0;
x(2)-[11-x(1)^2+x(3)]/10=0;
x(3)-[8-x(2)^3]/10=0'
用matlab求解非线性方程组,x(1)-[7+x(2)^2+4*x(3)]/12=0;x(2)-[11-x(1)^2+x(3)]/10=0;x(3)-[8-x(2)^3]/10=0'
matlab源程序为：
S=solve('x1-(7+x2^2+4*x3)/12=0','x2-(11-x1^2+x3)/10=0','x3-(8-x2^3)/10=0')
disp(S.x1)
disp(S.x2)
disp(S.x3)
S =
x1:[6x1 sym]
x2:[6x1 sym]
x3:[6x1 sym]

看看这个吧
其实应该一个命令就求出来了。
