Description Usage Arguments Value References Examples
This function is used in InfKern to produce the kernel matrix from functional data defined on the interval [0,1]. For further details see Section 7.4 of \insertCiteBKS2020USP.
1 | coeffs(X, Ntrunc)
|
X |
The discretised functions whose coefficients are required. This should be a matrix with one row per function, and with Ndisc columns, where Ndisc is the grid size of the discretisation. |
Ntrunc |
The number of coefficients that are required. The function returns coefficients 1,...,Ntrunc. |
The coefficients of X in its expansion in terms of sine functions. See \insertCiteBKS2020USP for more detail.
