Inverting a Matrix
Because the matrix in level 1 is square, you can find its inverse.
1: [[ 6 -2 -3 ]
[ -1 1 0 ]
[ -1 0 1 ]]
Finding the Determinant
Because the matrix in level 1 is square, you can find its determinant.
Multiplying Two Arrays
You can use the
function to multiply two matrices or a matrix and
a vector. (Use
to multiply two vectors, as described
Multiplying Two Matrices
The order of the arguments is important when multiplying two matri-
ces. The number of
in the matrix in level 2 must equal the
rows in the matrix in level 1. For example, you can calcu-
late the following matrix product.
