I am to create a function that uses FalsePosition (function shown below) to solve for f in the given equation. I think I'm missing some connections between my script and the function I'm trying to call.
Here is FalsePosition
This is my code:
function [root, fx, ea, iter] = falsepositionnew(y)
xl = 2500;
xu = 1000000;
es = 0.0000001;
maxit = 200;
Re = 10000:200000;
y = @(f, Re) 1/sqrt(f) - 4*log(Re*sqrt(f))+0.4; %equation given
for = i:numel(Re)
f(i) = falseposition(y,xl,xu,es,maxit);

%if true
for i = 1:numel(Re) % change this line

Notice the change in case for the function name in your code in for loop. And the name on the code snaphot you showed.

The function also outputs more variables than what its shown in for loop.
