Rank (linear algebra) - Wikipedia
网页The matrix has rank 2: the first two columns are linearly independent, so the rank is at least 2, but since the third is a linear combination of the first two (the first column plus the second), the three columns are linearly dependent so the rank must be less than 3.
How to visualize a rank-2 tensor? - Mathematics Stack Exchange
网页The notion (rank-2) "tensor" appears in many different parts of physics, e.g. stress tensor, moment of inertia tensor, etc. I know mathematically a tensor can be represented by a $3 \times 3$ matrix. But I can't grasp its geometrical picture — unlike scalar (a number) and vector (an arrow with direction and magnitude) which I can easily see ...

linear algebra - What's a "rank-two update" to a matrix?
网页2021年2月23日 · A rank-two update means we are adding a matrix whose rank is two, e.g. A + B A + B where B B is of rank two. The usefulness of this in connection with BFGS is that to retain symmetry, rank one updates would necessarily take the special form xxT x x T.
