初学者用matlab解二元二次方程组没有解,symsrx;[r,x]=solve('(r*(12660^2-sqrt(12660^4-4*x^2*1000000^2)))/(2*1000000*x^2)-0.0033=0','(12660^2*r*0.0033)/(r^2+0.0033^2*x^2)-1000000=0');rx结果r没有值,x是一个关于r的表达式,

Question

初学者用matlab解二元二次方程组没有解,
syms r x; [ r,x]=solve('(r*(12660^2-sqrt(12660^4-4*x^2*1000000^2)))/(2*1000000*x^2)-0.0033=0','(12660^2*r*0.0033)/(r^2+0.0033^2*x^2)-1000000=0');r x结果r没有值,x是一个关于r的表达式,

Answer 1

syms r x;
[r,x]=solve((r*(12660^2-sqrt(12660^4-4*x^2*1000000^2)))/(2*1000000*x^2)-0.0033==0, (12660^2*r*0.0033)/(r^2+0.0033^2*x^2)-1000000==0)
确实无解.检查题目吧.
