Consider a one-dimensional sequence (temporal or spatial) of samples from a many-species community. The sequence may exhibit no steady change, or gradual, steady change, or one or more abrupt, ...

If $A = (a_{ij})$ is an $n \times n$ irreducible matrix, then there are positive numbers $d_1, d_2, \cdots, d_n$ so that $\sum_k d_ia_{ik}d^{-1}_k = \sum_k d_ka_{ki}d ...

The most flexible way to connect signals and instruments is to use a switching matrix. In a test application, there often are many more signals than measuring instruments, necessitating signal ...

A recent paper set the fastest record for multiplying two matrices. But it also marks the end of the line for a method researchers have relied on for decades to make improvements. For computer ...
