Problems Extracting Stats

[rubgb]

When I try in Mathematica 11.3 {stat, result} = Stats[Int[(a + b*Sqrt[x])^d, x]];

I get the following error message:

Set::shape: Lists {stat,result} and -((2 a (a+b Sqrt[x])^(1+d))/(b^2 (1+d)))+(2 (a+b Sqrt[x])^(2+d))/(b^2 (2+d)) are not the same shape.

Any alternatives?

I'm sorry, this is my fault because I did not update the documentation on the website accordingly. We unified the behavior of Stats, Steps, and Step and it is mentioned in the release message. This means, per default, all three functions will print their information because this is the most common use-case.

If you want to have the information returned in the form {info, result}, you can use the option RubiPrintInformation -> False with all three functions Stats, Steps, and Step. So for you this means you need to use

{stat, result} = Stats[Int[(a + b*Sqrt[x])^d, x], RubiPrintInformation -> False]

Edit

I have also fixed the website now.

Thanks for the clarification
