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.
