I used a code for bisection method, which supposed to be working, unfortunately it´s not and I do not know what is the problem. This code also includes user defined precision and a counter for number of iterations. The error I´m getting is for the last line in the code: Undefined function or variable 'c'.
a=-5;b=0;tol = input('What precision would you like? ','s')fa=a^3-20+exp(a);fb=b^3-20+exp(b);counter=1while abs(b-a) > tol c=(a+b)/2; fx = c*c-2; if fa*fc<0 b=c; fb=fc; elseif fb*fc<0 a=c; fa=fc; else break end fprintf('Just finished iteration #%d\n', counter); counter=counter+1;endx=c;
