I cannot detect an error on Newton Method.
显示 更早的评论
I am programming the Newton Method, but I doesn´t work. Someone could help me. I would really appreciate it.
I also want to plot the function but it does not work either.
I did the following:
x = a:0.01:x+10
plot (x,f(x))
And it did not work, because no graphic appeared.
I attached the code.

function [x,n,error] = NewtonRaphson(f,a,eps_f,eps_x,df,maxits)
%>> df
% remaining code
x = a:0.01:x+10
plot (x,f(x))
end
Pass the anonymous function df into function NewtonRaphson

Or you can plot it outside the function as below
[x,n,error] = NewtonRaphson(f,a,eps_f,eps_x,df,maxits)
x = a:0.01:x+10;
plot (x,f(x))
%--------------------------------------------------->> df as argument
function [x,n,error] = NewtonRaphson(f,a,eps_f,eps_x,df,maxits)
% code
end
