kron {assist}

Calculate reproducing kernels for one-dimensional space

Description

Return a matrix evaluating reproducing kernels for the one-dimensional space usually spanned by a vector

Usage

 kron(x,y=x)

Arguments

x

a vector or a list of numerical values which spans the one-dimensional space.

y

a vector or a list of numerical values. Default is x.

Value

a matrix with the numbers of row and column equal to the length of x and y respectively. The [i, j] element is the reproducing kernel evaluated at the ith element of x and jth element of y.
