Can someone pleas help me whith this problem.
Write a function that numerically finds the zero crossing of the
function f. Inputs to the function are the name of the function to be
analyzed, together with xl and xu such that
f(xl) < 0 < f(xu)
Also, the desired accuracy of the solution (in xzero) is given.
Use the half-interval method:
1
1. Let x = - ( x + x ).
m 2 l u
2. If f( x ) < 0 then let x = x , else let x = x .
m l m u m
3. Repeat 1. and 2. until the desired solution accuracy is obtained.
Limit the iteration count to 100!
Syntax: xzero = findzero('fun', xl, xu, d)
