creating a function to solve non linear equations using simple iteration method

12 views (last 30 days)
Create a Matlab function named (solveIteration) for solving a non-linear equation using (Simple iteration method) and takes the following inputs: g: function, x0 initial guess TolX as Termination tolerance on the function value, a positive scalar (when to stop iteration) and Maxiter as the max number of iterations if reached means the function has no solution The function returns the following outputs : x as a root(s) of the equation ,error as error message if the equation has no solutions Function seems like below one: function [x,error] = solveIteration(g,x0,TolX,MaxIter) ...
any hints ??

function [x,err] = solveit(g,x0,to,max)
syms x
x1=x0(1);
while subs(diff(g),x,x0)<=1
n=n+1;
if x1-subs(g,x,x1)<= to && n<= max
x1=subs(g,x,x1);
x=x1;
break
else
x=err;
end
end
end
