So I have this code I need too use on my a function.
I have made m. function file with the function I want to calculate.
f=@(x)(x-2.5).*exp(-0.5*(x-2).^2)+0.2;x=my_bisect(f,[-1,0],1e-5);m =(a+b)/2; disp(m);
And in another file I have this code:
function m=my_bisect(funktion, int , tol )a = int (-1);b = int (0);fa =funktion(a) ;fb =funktion(b) ; disp(fa)disp(fb)msg=sprintf('??? error.');while b-a > tol m = (a+b)/2; fm = funktion(m); if fm==0 disp(msg) return end if fa * fm < 0 b = m; fb = fm; else a = m; fa = fm; endend
When I try running function file to find m Matlab returns: Attempted to access int(-1); index must be a positive integer or logical.
What is wrong?
