# numpy.polynomial.chebyshev.chebweight#

polynomial.chebyshev.chebweight(x)[source]#

The weight function of the Chebyshev polynomials.

The weight function is $$1/\sqrt{1 - x^2}$$ and the interval of integration is $$[-1, 1]$$. The Chebyshev polynomials are orthogonal, but not normalized, with respect to this weight function.

Parameters
xarray_like

Values at which the weight function will be computed.

Returns
wndarray

The weight function at x.

Notes

New in version 1.7.0.
