Hi!
I would like you to help me with the MetLab code below. I do not know where I am wrong. Can a member help me?
Code:
xl=1 xu=2 x1=-4:0.01:4; y=polyval(p1,x1); plot(x1,y1) grid xlabel('oi times tou x') ylabel ('oi times tou y') for i=1:16 mesi=(xu+xl)/2; timixu=polyval (p1,xu); timixl=polyval (p1,xl); timimesi=polyval(p1,mesi); if timimesi*timixu<0 xl=mesi result=mesi; else xu=mesi result=mesi; end end
p2=[-1 2,71^1 -4] xl=1 xu=2 sfalma=1 i=0 resultold=2 x2=-4:0,01:4; y2=polyval(p2,x2); plot(x2,y2) grid xlabel('oi times tou x') ylabel ('oi times tou y') while sfalma>0,00001 mesi=(xu+xl)/2 timixu=polyval (p2,xu) timixl=polyval (p2,xl) timimesi=polyval (p2,mesi) if (timimesi*timixu<0) xl=mesi else xu=mesi end result=mesi; sfalma=abs((result-resultold)/result*100) result=resultold i=i+1 end]
