f=@ (x) cos(x)+1/(1+x^2);

fd=@(x) -sin(x)-2*x/(1+x^2);

root=NewtonRaphson(f,fd,1.5,0.05,10);

function Xs=NewtonRaphson(Fun,Funder,Xo,Err,imax)

disp('Values in each iteration : ')

for(i=1:imax)

Xi=Xo-Fun(Xo)/Funder(Xo);

disp(Xi) if(abs((Xi-Xo)/Xo)<Err)

Xs=Xi; break end X0=Xi;

end

if(i==imax)

fprint('Solution not obtaind in %i iteration',imax)

Xs=('No Answer');

end

Well, what are you seeing that is incorrect?

Some suggestions - the code is formatted incorrectly, causing runtime errors.

There is no MATLAB function called fprint. Did you instead mean to use fprintf?

R2007b does not permit functions to be defined in scripts.

The feature of defining functions in scripts was introduced with R2016b:
