Hi, I've been trying to do this code on matlab but keep getting error.

I want to integrate this function fun= @(t,Mycp,L,r)Mycp*L*exp(-r*t) with n= integral(@(t)fun(t,Mycp,L,r),0,100).

The interval t=[0 100]

The parameters are Mycp=[0 10], L=1,r=0.03,

Please help!

Use the 'ArrayValued' (link) name-value pair:

Mycp = [0 10];
L = 1;
r = 0.03;
fun = @(t,Mycp,L,r)Mycp*L*exp(-r*t);
n = integral(@(t)fun(t,Mycp,L,r),0,100, 'ArrayValued',1)

producing:

n =
                         0          316.737643877379
