You can get solutions with the least-squares method even if overdetermined systems (the number of equations is greater than the number of variables). It is written in C++. C++11 or later is required.

Abstract: An H-matrix accelerated direct solver employing the high-order Chebyshev-based Boundary Integral Equation (CBIE) method has been formulated, tested, and profiled for performance on high ...

Rice grain is considered a complex matrix. Thus, the extraction and clean-up steps must be carefully studied. The most frequent strategies are based on liquid-liquid; solid-phase; as well as ...

Abstract: Here, we describe some of the basic steps for solving mathematical equations with a metadevice, i.e., a subwavelength network that allows for the inversion of any desired matrix. The device ...

When artificial intelligence tools can draft essays and solve problems in seconds, it can be hard to resist the temptation to take shortcuts.
