method

polynomial.polynomial.Polynomial.cutdeg(deg)[source]#

Truncate series to the given degree.

Reduce the degree of the series to deg by discarding the high order terms. If deg is greater than the current degree a copy of the current series is returned. This can be useful in least squares where the coefficients of the high degree terms may be very small.

Parameters:
degnon-negative int

The series is reduced to degree deg by discarding the high order terms. The value of deg must be a non-negative integer.

Returns:
new_seriesseries

New instance of series with reduced degree.
