Excel can solve equations through several of its mathematical functions, but the single Excel tool that works on the largest variety of equations is the program's Solver Add-in. This tool reads an ...

But linear systems can do more than just count chickens and pigs. They crop up in many practical settings, where building a sturdier bridge or a stealthier aircraft can involve solving systems with ...

Solve the PDE and you get a formula that describes something about the system. In this case, the solution may be a formula that lets you calculate the flow field at at different times. Some PDEs can ...

The result is a solution to the system of linear equations encoded as the quantum state |x〉. Producing a quantum state proportional to A −1 | b 〉 does not, by itself, solve the task at hand.
