I tried my equation like below :
fzero(@(x) 20000/x(1-x)*(1+0.1*(1.523*(1-x)/x)^0.75)*0.005093-x(1-x)*9768.4, 0)
I didn`t touch anything with matlab. and I just tried that equation as soon as I opened my matlab program.
so I don`t know why there is an error like that.
please somebody help me... I`m a beginner of matlab.
