Create list of Chebyshev polynomials
Description
This function returns a list with n + 1 elements containing
the order k Chebyshev polynomials of the first kind, C_k \left( x\right),
for orders k = 0,\;1,\; \ldots ,\;n.
Usage
chebyshev.c.polynomials(n, normalized=FALSE)
Arguments
n |
integer value for the highest polynomial order |
normalized |
a boolean value which, if TRUE, returns a list of normalized orthogonal polynomials |
Details
The function chebyshev.c.recurrences produces a data frame with the recurrence relation parameters
for the polynomials. If the normalized argument is FALSE, the
function orthogonal.polynomials is used to construct the list of orthogonal polynomial objects.
Otherwise, the function orthonormal.polynomials is used to construct the
list of orthonormal polynomial objects.
Value
A list of n + 1 polynomial objects
1 |
order 0 Chebyshev polynomial |
2 |
order 1 Chebyshev polynomial |
...
n+1 |
order |
