Quantlet: createldo
Description: creates a linear differential operator (LDO) object

Usage: LDO = createldo(ldoname,derivs)
Input:
ldoname name of the proc-endp environment where the linear differential operator (LDO) is defined
derivs vector containing the order of derivatives needed for the LDO
Output:
LDO list, LDO object, a list containing ldoname and derivs

Example:
library("fda")
proc(wt) = LDO1(evalarg)
  wt = matrix(2, rows(evalarg), cols(evalarg))
  wt[1] = 1.25 .* evalarg
  wt[2] = 0.5 .* evalarg^2
endp
LDO = createldo("LDO1", #(1, 3))
LDO

Result:
Contents of LDO.ldoname

[1,] "LDO1"

Contents of LDO.derivs

[1,]        1
[2,]        3
