find_independents_backward
- compas_tno.algorithms.find_independents_backward(E, nind=None, tol=None)[source]
Find independent edges of the matrix E with the backward method. The last columns of the matrix are removed sequentially and the rank is checked. Everytime thae rank does not decrease, the edge is selected as independent.
- Parameters
E (array) – Equilibrium matrix.
nind (ind) – Number of independent to stop the process, if known in advance, by default None.
tol (float) – Tolerance for small singular values. Default is None.
- Returns
ind (list) – Independent columns.
