;+
; FUNCTION TRUNCATED_RAMP,X
; Computes a truncated ramp function for any list of values represented
; by the vector x. The ramp is zero outside the range [-b,b]
;
; USAGE:
; x=FINDGEN(1001)/20-25 CREATE A VECTOR ON THE INTERVAL [-25,25]
; y=TRUNCATED_RAMP((x-8)/5,3) Construct a function that is shifted and stretched
