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: It is known that both the physical domain in size and problem complexity should also be considered to decrease more and more computational resources, especially for a large-scale complicated ...

Abstract: The challenging task of solving inverse scattering problems (ISPs) is due to their inherent ill-posedness and nonlinearity. To alleviate ill-posedness, a novel hybrid regularization method ...
