numpy.polynomial.laguerre.Laguerre.cutdeg

method

Laguerre.cutdeg(deg)[源代码]

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:
deg : non-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_series : series

New instance of series with reduced degree.
