buffer (signal)?

[Sciss]

hi,

i am trying to run a function that was written for matlab. it breaks  
because the function 'buffer' is missing, something that creates an  
overlapped-chunk version of a vector. on octave-forge's documentation  
site, it is stated:

"buffer  [signal] -- not implemented"

... so i assume this function is missing? i installed the signal  
package but no luck. any clues how i can get a 'buffer' function for  
octave?

thanks a lot! cheers, -sciss-
