A rank-one matrix is the product of two vectors

Simpler definition for kernel, image, and rank of transformation matrix?

Matrices with rank exactly r as variety

If the rank of $A$ is equal to the number of non-zero eigenvalues, do $A$ and $A^2$ have the same rank?

Paradox on the derivative of the rank of a matrix?

If $AB=0$ prove that $\mathrm{rank}(A)+\mathrm{rank}(B)\leq n$

Show $\operatorname{rank}(A) + \operatorname{rank}(B) \ge \operatorname{rank}(A+B)$

Relation between determinant and matrix rank

Prove $\operatorname{rank}A^TA=\operatorname{rank}A$ for any $A\in M_{m \times n}$

Looking for an intuitive explanation why the row rank is equal to the column rank for a matrix
