What is wrong in this code?!

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

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?

ya i mean fprintf ,but when i run the code,it not work and give me error

R2007b does not permit functions to be defined in scripts.

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