solving non-linear equation
显示 更早的评论
Hi
I am solving for x in this equation.
where J1 is Bessel function of first kind order one. Below s my code, however i am notsure if this is the right way to solve an equation in matlab. can anyone please help me to check my code.
Thanks
clear all
syms x
b=371.05*10^-6;
num=sqrt(-8*b*abs(x));
den=sqrt(-2*b*abs(x));
eqn = 1.4*sqrt((besselj(1,num))/(den))==x;
solvx = solve(eqn,x);
vpa(solvx)

Go directly for vpasolve instead of solve as it is not feasible to expect a closed form solution for that.
