iFit/zeros

PURPOSE

SYNOPSIS

DESCRIPTION

 s = zeros(s,N,M,P,...) : initialize an iData array

   @iData/zeros function to create an array of 's' iData objects
   The object 's' is duplicated into an array. Use s=iData to get an empty array.

 input:  s: object or array (iData)
 output: b: object or array (iData)
 ex: zeros(iData,5,5) will create a 5-by-5 empty iData array
     zeros(s,5,5) will return a 5-by-5 array filled with 's'
