Create Chebyshev spectral differentiation matrix

Description

Chebyshev spectral differentiation matrix of order n. k determines the character of the output matrix. For either form, the eigenvector matrix is ill-conditioned.

Usage

chebspec(n, k = NULL)

Arguments

`n`	order of the matrix.
`k`	`k=0` is the default, no boundary conditions. The matrix is similar to a Jordan block of size `n` with eigenvalue 0. If `k=1`, the matrix is nonsingular and well-conditioned, and its eigenvalues have negative real parts.
