trying to get numerical answer for a variable equation
显示 更早的评论
Zarc=([(Z*(Zarc*(tan(ThetaR1))))/((8.2+((x-1)*0.05))-(Zarc(tan(ThetaR1))))])
This is my equation and I am trying to use code to find out what the variable is for Zarc. I am tyring to intergrate it but having multiple errors come up. Needs to be in the form of a loop i know.
Thanks,
Amanda

syms Zarc Z ThetaR1 x
solve(Zarc==(((Z*(Zarc*(tan(ThetaR1))))/((8.2+((x-1)*0.05))-(Zarc*(tan(ThetaR1)))))),Zarc)

There are two solutions for Zarc:
- 0
- (x - 20*Z*tan(ThetaR1) + 163)/(20*tan(ThetaR1))
You could also use something like fzero:
fzero( @(Zarc) (((Z*(Zarc*(tan(ThetaR1))))/((8.2+((x-1)*0.05))-(Zarc*(tan(ThetaR1)))))) - Zarc, SomeInitialGuess)
