Simple problem of MATLAB related to the fzero function

To solve this you need to use fzero function

You might need global function

All I need is correct code to solve this problem

You guys should give me 2 scripts of the code

You guys can ignore the part [an appropriately modified form ~~ the problem 3]

Solution

clc
clear all

%%

r=0:0.5:10;
tanroot=zeros(size(r));

x0=[0,1.57]; % interval

for i=1:length(r)
fun= @(x) x*tan(x)-r(i);
x=fzero(fun,x0);
  
tanroot(i)=x;
  
end
