Problem to solve integration

Hi all, I having an issue to solve this problem.

clc

clear

close all

syms x

f = @x sin(x);

a = 0;

b = pi;

prompt = ('Enter the number of subinterval,n:');

n = input(prompt);

function result_integration = midpoint(f, a, b, n)

h = (b-a)/n;

result = 0;

for i = 0:(n-1)

result = result + f((a + h/2) + i*h);

end

result_integration = h*result;

end

I would be very grateful to those can solve this matter. Thanks!

Change this —

f = @x sin(x);

to this —

f = @(x) sin(x);

That should work.
