hey
i have a question for u guys.
i have wrriten this code:
function[a]=search_root_3(x,e)
f1=x^3-10*x^2+15*x+3;
f11=diff(x^3-10*x^2+15*x+3,x,1);
if abs(f1)<=e
fprintf('the root is %d% \n');
return
end
while abs(f1)>=e
x=x-(f1/f11);
f1=x^3-10*x^2+15*x+3;
f11=diff(x^3-10*x^2+15*x+3,x,1);
end
a=x;
end
the goal is to find the root.
when i am trying to run this code i getting the next eror even though i have used f1 (exact form) in other codes seccessfully:
>> [a]=search_root_3(x1,e)
? Error using ==> mpower
Inputs must be a scalar and a square matrix.
Error in ==> search_root_3 at 10
f1=x^3-10*x^2+15*x+3;
i will be glad to get some help
thanx
