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 ...

Algorithms have been used throughout the world’s civilizations to perform fundamental operations for thousands of years. However, discovering algorithms is highly challenging. Matrix multiplication is ...

Computer scientists are a demanding bunch. For them, it’s not enough to get the right answer to a problem — the goal, almost always, is to get the answer as efficiently as possible. Take the act of ...

Solution: det (A) = −5, and for n×n matrix adj (A) has determinant (det A)^ (n−1). Here n = 3, so det (B) = (−5)^ (2) = 25. For feedback or story ideas, reach us at [email protected] ...

It's been a mere 18 years since we last decided whether to take the blue pill or the red pill, but with nearly two decades of expanded lore and cult classic status to explore, Lana Wachowski is back ...

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 switching matrix used in a test system connects a signal on a particular column to an instrument on a certain row. Typically, there are more signals than instruments, so several voltage measurements ...
