I'm trying to create a function that finds the root of an equation , error , and number of iterations by (bisection method ) but I'm getting errors that I don't understand

So I did my code but errors kept showing and i don't know how to fix the problem , so a little help will be appreciated .

what I want to do is to have two M-files (scripts) one contain the function that calculates the root of an equation X , the error e , and the number of iterations i as a function of the input X0 , X1 and F(equation in term of X ) .the second M-file that i will run gives the input values and call the function of the other M file.

so this my code in the first M-file ( named: men_bisect.m)

function [X,i,e]= mem_bisect(F,Xo,X1)
X=(Xo+X1)/2;
% X=feval(F,X);
if(F(Xo)==0)
    Xo=X;
end

if(F(X1)==0)
    X1=X;
end

X=(Xo+X1)/2 ;

if(F(X)==0)
end

if(F(Xo)*F(X1)>0)
disp('A solution is not guaranteed because f(Xo) * f(X1)>0')
end

if(F(Xo)*F(X1)<0)
    X=(Xo+X1)/2; 
    i=0;
    eps=1*10.^-5 ;
    e=abs(F(X));
    while(i<1000 && e>eps)

          if((F(X)*F(X1))<0)
              Xo=X;
          else
              X1=X;
          end
          i=i+1;
          X=(Xo+X1)/2;
          e=abs(F(X));

      end 

     disp('the root is',X,'and the error is ',e,'and the number of iterations is',i);

end

and this is my second M-file ( named : mem.m ) that I will run from:

clear all
clear variables 
clc
% The range
Xo=0;
X1=1.5;
% The equation
a=@(X) X;
F=@(X)(sin(2*pi*X)+exp(1.2*X)+X-2.5);
% Calling the function mem_bisect
mem_bisect(F,Xo,X1);

I kept getting these errors :

?? Error using ==> disp
Too many input arguments.

Error in ==> mem_bisect at 40
   disp('the root is',X,'and the error is ',e,'and the number of iterations is',i);

Error in ==> men at 11
mem_bisect(F,Xo,X1);

I think the problem is with the function and the order of the code but i don't to how to fix them.

     fprintf('the root is %g and the error is %g and the number of iterations is %d\n', X, e, i);
