Example: Let $\mathbfv = \beginbmatrix 1 \ 2 \endbmatrix$ and $\mathbfw = \beginbmatrix 3 \ 4 \endbmatrix$. Then $\mathbfv + \mathbfw = \beginbmatrix 4 \ 6 \endbmatrix$.
Transforming matrices into upper triangular form to find solutions.

: Short summary sheets for every video lecture in the 18.06 Scholar course, perfect for quick reviews. Access these through the MIT 18.06SC Resource Index . 2. Formal Textbook Supplements
Neural networks rely entirely on weights stored as matrices. Gradient descent requires an understanding of multi-dimensional vector calculus and matrix derivatives. Example: Let $\mathbfv = \beginbmatrix 1 \ 2
SVD breaks any matrix down into two orthogonal bases (left and right singular vectors) and a diagonal matrix of scaling factors (singular values).
