trapzmat | R Documentation |
The first two arguments are matrices of values of two functional data objects of the same fine mesh of argument values. The mesh is assumed to be equally spaced.
trapzmat(X,Y,delta=1,wt=rep(1,n))
X |
The first matrix of functional data object values over a fine mesh. |
Y |
The second matrix of functional data object values over the same fine mesh. |
delta |
The difference between adjacent argument values, assumed to be a constant. |
wt |
An optional vector of weights for the products of pairs of argument values, otherwise assumed to be all ones. |
A matrix of approximate inner products. The number of rows the number of columns of
X
and the number of columns is the number of columns of Y
