I am trying to follow the examples of the linear algebra documentation:

https://docs.julialang.org/en/v1/stdlib/LinearAlgebra/#Linear-Algebra-1

But when I try to compute the eigenvalues or eigenvectors I get:

ERROR: UndefVarError: eigvecs not defined

I am literally copying and pasting the example into the REPL, so either there it is not clear that some package must be loaded before using these functions, or there is a bug. I am using v1.0

Thank you very much.
