Module rusty_compression::row_interp_decomp

Data structure for Row Interpolative Decomposition

A row interpolative decomposition of a matrix $A\in\mathbb{C}^{m\times n}$ is defined as $$ A\approx XR $$ with $R\in\mathbb{C}^{k\times n}$ being a matrix whose rows form a subset of the rows of $A$, and $X\in\mathbb{R}^{m\times k}$. The rows of $R$ are obtained from the corresponding rows of $A$ via an index vector row_ind. If row_ind[i] = j then the ith row of $R$ is identical to the jth row of $A$.
