Undefined operator '-' for input arguments of type 'function_handle'.

me sale un error y no se como resolverlo

can you help me with my code, i have a error a idont know how to solve it

clc

funcioon=@(x) x.^2-x*100+1;

CI=1000;

delta=0.0001;

error=100;

n=0;

while error>0.00000001

funci=funcioon(CI);

funmasdel=funcioon(CI+delta);

derivada=(funmasdel-funci)/delta;

Xn=(CI-funcioon)/derivada

error=abs(funcioon(Xn))

CI=xn

n=n+1

if n>500000

break

end

end

You have to evaluate a function if you want to use it in a computation.

For example —

Xn=(CI-funci)/derivada;

would work.

Also, since MATLAB is case-sensitive, change this line to:

CI=Xn;
