How can i derivate/integrate a function f(x) in Simulink using MATLAB?

Hello, i can't run through this problem. I have a function:

    y=1-exp((-x/a)^b)

I would like to get its derivate and, after that, integrate the new function multiplied by (pi/6)*x^3. I did the derivate using Matlab Command Window then i tried to integrate with MATLAB, but i solve it only in a script, which couldn't actually introduce in my Simulink model.

 f=@intVolums;
q=integral(f,5,100);
function y = intVolums(x)
k1=0.65;
k2=-0.6;
k3=1;
y=(pi./6).*(x.^3).*k1.*exp(k2.*(x.^k3));
end

k1,k2,k3 are costant parameters obtained by the first function derivation. I'm new in Simulink modelling so i need help or to have Simulink solve these operations, or to introduce the scripts I made with MATLAB into the model. It is quite urgent. Thanks

As you have already written the MATLAB script for the task. You can directly use "MATLAB function block" in Simulink and insert your code into that block.

You can read more on "MATLAB function block":
