====== Chop ======

###
G2 = ResponseFunction.Chop(G1) removes (sets to zero) all numbers form $G_1$ that are in absolute value smaller than epsilon. Chop does not change the [[documentation:language_reference:objects:responsefunction:functions:changetype|type]] of the response function. 
###


===== Input =====

  * G : a response function
  * epsilon : (optional) the smallest number considered different from zero. If not given the standard value is 10 times machine precision. 

===== Output =====

  * a copy of G with small numbers replaced by zero

===== Options =====

  * Deflate : a boolean that determines if poles with zero weight are completely removed from the response function or if they are kept.
