matlab solve 函数 求 (1+0.2x^2)^(-0.5)/x=4.2336我用的是x=solve('(5./6).^3./x.*(1+0.2.*x.^2).^(-0.5)-2.45=0','x')但是报错Undefined function 'solve' for input arguments of type 'char'.Error in hw5 (line 2)x=solve('(5./6).^3./x.*(1+0.2.*x

matlab solve 函数 求 (1+0.2x^2)^(-0.5)/x=4.2336
我用的是
x=solve('(5./6).^3./x.*(1+0.2.*x.^2).^(-0.5)-2.45=0','x')
但是报错
Undefined function 'solve' for input arguments of type 'char'.
Error in hw5 (line 2)
