Hi everyone, i have a problem with dimensions: I am programing conjugate gradient algorithm, unfortunatly, when the result is skalar, sage still handles it a matrix 1x1, and as a result i can not use multiplication. How can i fix it, maybe there is a good tutorial or a book for sage and linear algebra.

here is the work so far:

Thank you in advance
