Accessing Method Documentation

For methods, which cannot be called by themself, we can find their documentation by adding a question mark after appending the method to a relevant object. Here, we'll access the documentation fro the rref() method, which is used on matrices:

Code

A = matrix(QQ, [[1, 2], [3, 4]])
A.rref?
