`numpy.polynomial.chebyshev:_cseries_to_zseries`

source: build-install/usr/lib/python3.14/site-packages/numpy/polynomial/chebyshev.py :131

Signature

def _cseries_to_zseries ( c )

Summary

Convert Chebyshev series to z-series.

Extended Summary

Convert a Chebyshev series to the equivalent z-series. The result is never an empty array. The dtype of the return is the same as that of the input. No checks are run on the arguments as this routine is for internal use.

Parameters

c : 1-D ndarray: Chebyshev coefficients, ordered from low to high

Returns

zs : 1-D ndarray: Odd length symmetric z-series, ordered from low to high.
