function WMKIARRY, a, b, c
;+
; NAME:
; 	WMKIARRY
;
; PURPOSE:
;	This function creates an INTEGER INDEX array with the same notation that 
;	Matlab uses in creating one, i.e. y = a:b:c.
;
; CATEGORY:
;	Wavelets
;
; CALLING SEQUENCE:
;    y = WMKIARRY( a, b, c)
;
; INPUTS:
;	a: index of 1st element.
;	b:    increment (usually 1).
;	c:  index of last element.
;
; OUTPUTS:
;    y:	An array of index values.
;
; NOTES:
;	Matlab indices for arrays begin with 1, IDL begins
;	with 0. This routine assumes that the array created
;	has index-1 of what Matlab uses. I.e. If Matlab
;	assumes an index array of: [2,6,10,14,18], this
;	routine creates: [1,5,9,13,17].
;
; SEE ALSO: 
;	wmkfarry (arrays of fractional values)
;
; EXAMPLE:
;IDL> t=WMKIARRY(1,1,5)
;IDL> print, t
;       0       1       2       3       4
