I can calculate the integral for I1 but not for I2,I3 and I4. I'm new to matlab. I get the error as shown below. But when I plot the graph it's fine. Thanks
Index exceeds matrix dimensions.
Error in Q1d>@(x)(p2(1)*x((6:22)+1).^4)+(p2(2)*x((6:22)+1).^3)+p2(3)*x((6:22)+1).^2+p2(4)*x((6:22)+1)+p2(5)
Error in CompSimp (line 26)
fx = func(x);
Error in Q1d (line 61)
I2 = CompSimp(k,a,b,17)

It's difficult to answer in great details with so little information, but either x has less than 23 elements when your program reaches line 26 of CompSlim, or p2 has less than 5 elements when the anonymous function is declared.
