We can access the scalar element aijaij of a matrix AA in :eqref:
eq_matrix_defby specifying the indices for the row (ii) and column (jj), such as [A]ij[A]ij. When the scalar elements of a matrix AA, such as in :eqref:
what is :eqref:
Hey @gpk2000, thanks for pointing out the typo. The equation doesn’t render properly, it should mean to be equation 2.3.2.
Thanks. Now it’s fixed. See comments in https://github.com/d2l-ai/d2l-en/issues/1448
Here are a few norm examples for the MXNet folks:
[nav] In : np.linalg.norm(np.arange(24))
[nav] In : np.sqrt(np.sum(np.arange(24)**2))
[ins] In : np.linalg.norm(np.arange(24), ord=1)
I don’t know where I am supposed to start thinking from to answer question 7, can someone give me some pointers?
