Linear systems
Given a system , this simulator finds all its solutions:
it first checks consistency and the number of solutions with the Rouché-Capelli theorem,
then looks for shortcuts by eye (evident inconsistencies, immediate particular solutions,
relations among the columns), and in any case solves it with Gauss-Jordan on the augmented
matrix, all the way to the parametric form of the result. All computations use exact
rational arithmetic; the cells of and also accept parameters (for example
k or t), with a case analysis on the critical values.
Step 1 — SET THE SYSTEM DIMENSIONS
\(\large\times\)
Step 2 — FILL IN THE MATRIX \(A\) AND THE RIGHT-HAND SIDE \(\mathbf{b}\)
We look for ALL solutions of \(A \cdot \mathbf{x}=\mathbf{b}\): shortcuts first, then in any case the standard route with Gauss-Jordan and the parametric form of the result.
