I don't know why MATLAB don't give me the answer for this integral

I'm a beginner with Matlab, and I don't know why MATLAB don't give me the answer for this integral

int((6719222573537927*exp((5*x)/2 - (15*u)/2)*(u + x)^(3/2)*(u - x)^19)/576460752303423488, u, abs(x), Inf).

Why? How can we get the result integration? Anyone could help me, please?

Why don't you write the actual integral expression here? It would be easy to people to help you.

[Walter Roberson]

The expression is simply too complicated for MATLAB to integrate symbolically. There are other software vendors and tools that are more complete. Two of the leading commercial alternatives are Maple (Maplesoft) and Mathematica (Wolfram Research)

Note: Mathematica cannot integrate this expression, but Maple can.

I tried it with Maple but I can't get the answer. Could you please help me how I can deal with this?
