calcBasisIntegrals {MFPCA} | R Documentation |
Utility function that calculates matrix of basis-scalar products (one dimension)
Description
If the element X^{(j)}
is expanded in basis functions b_i^{(j)}(t),~ i = 1, \ldots, K_j
,
this function calculates the K_j \times K_j
matrix B^{(jj)}
with entries
B^{(jj)}_{mn} = \int_{\mathcal{T_j}} b_m^{(j)}(t) b_n^{(j)}(t) \mathrm{d} t
.
Usage
calcBasisIntegrals(basisFunctions, dimSupp, argvals)
Arguments
basisFunctions |
Array of |
dimSupp |
dimension of the support of the basis functions (1 or 2) |
argvals |
List of corresponding x-values. |
Value
A matrix containing the scalar product of all combinations of basis functions (matrix B^{(j)}
)
Warning
This function is implemented only for functions on one- or two-dimensional domains.
