如何在Matlab中求解具有双系数的符号方程式? [英] How to solve symbolic equation with double coefficients in matlab?

问题描述

我有二次方程1/x = 1/(a-x)+ 1/(3 * a -x)

I have quadratic equation 1/x = 1/(a-x) + 1/(3*a -x)

我想在matlab中解决它:

I want to solve it in matlab:

solve('1/x=1/(a-x)+1/(3*a-x)', 'x')
ans =
 (4/3+1/3*7^(1/2))*a
 (4/3-1/3*7^(1/2))*a

有什么方法可以用浮点系数求解方程?喜欢

Is there any way to solve equation with float coefficient? Like

ans = 
  2.215250437021530*a
  0.451416229645136*a

推荐答案

显然，double(ans)应该为您转换.
