Resolución de sistemas lineales y no lineales

open access: yes, 2017
[en] The problem of solving systems of equations is one of the oldest and with more applications in a variety of situations. A first example is finding a curve to which belong $n$ fixed points $(x_{i}, y_{i}), 1\leq i \leq n$. For this, $P n$ the usual procedure consists in searching for a polynomial of degree $n, p(z) = \sum^{n}_{i=0} ai\cdot z_{i}$ ,
