How do I calculate this definite integral in matlab

hello. I want to calculate this integral. But it does not answer.

please check it. thanks

clc
clear

syms x 
f = (124-x)^3/((12.152-2*x)^2*(1.24-x));

F = int(f, x, 0, 4.23)

Use "integral" in MATLAB to compute (help integral in MATLAB)

Try trapz

I wrote this code but it did not answer.

clc
clear

n=100
a=0
b=4.23
x=linspace(0,4.23,n)
f =@(x)(124-x).^3/((12.152-2*x).^2*(1.24-x));

trapz(x,f(x));

You forgot about the dot

Answer 2

When I encounter a problem integrating, one of my first thoughts is to look at the function I'm trying to integrate over the interval of integration.

syms x 
f = (124-x)^3/((12.152-2*x)^2*(1.24-x));
fplot(f, [0, 4.23])

That section around x = 1.24 could prove problematic.

I calculated this integral with a site and it gave me the number -72828.4694525021.

Now I want to calculate with MATLAB and compare the answers.
