1  generate_knots(knots.number = NULL, d, lower = NULL, upper = NULL)

knots.number 
Array of size d containing integers.

d 
Integer. Number of dimensions. This is also equal to 
lower 
Array of size d containing the lower bounds of the input domain. 
upper 
Array of size d containing the upper bounds of the input domain. 
The knots are placed at the boundary of the domain, so, if we work in the unit hypercube then
the array result[[i]]
will be c(0,1)
if knots.number[i] = 2
,
c(0,0.5,1)
if knots.number[i] = 3
, c(0,1/3,2/3,1)
if knots.number[i] = 4
and so on.
A list with d fields. Field i is an array of size knots.number[i]
when there is 2 knots
or more, and is 0 otherwise.
