`scipy.spatial._qhull:HalfspaceIntersection.add_halfspaces`

Signature

def add_halfspaces ( halfspaces , restart = False )

Summary

Process a set of additional new halfspaces.

Parameters

halfspaces : ndarray of double, shape (n_new_ineq, ndim+1): New halfspaces to add. The dimensionality (ndim) should match that of the initial halfspaces. Like in the constructor, these are stacked inequalites of the form Ax + b <= 0 in format [A; b]. The original feasible point must also be feasible for these new inequalities.
restart : bool, optional: Whether to restart processing from scratch, rather than adding halfspaces incrementally.

Raises

: QhullError: Raised when Qhull encounters an error condition, such as geometrical degeneracy when options to resolve are not enabled.

Notes

You need to specify incremental=True when constructing the object to be able to add halfspaces incrementally. Incremental addition of halfspaces is also not possible after close has been called.
