numpy.polynomial.polyutils.trimseq(seq)[source]

Remove small Poly series coefficients.

Parameters:

seq : sequence

Sequence of Poly series coefficients. This routine fails for empty sequences.

Returns:

series : sequence

Subsequence with trailing zeros removed. If the resulting sequence would be empty, return the first element. The returned sequence may or may not be a view.

Notes

Do not lose the type info if the sequence contains unknown objects.
