find_independents_backward
- compas_tno.algorithms.find_independents_backward(E, nind=None, tol=None)
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:
- Earray
Equilibrium matrix.
- nindint
Number of independent to stop the process, if known in advance, by default None.
- tolfloat
Tolerance for small singular values. Default is None.
- Returns:
- indlist
Independent columns.
