  Operateur CVOL                           Voir aussi :
    --------------   
    LREEL1  = CVOL LREEL2 LREEL3 (('NPNE' ENTI1) MOT1) ;



    Description :
    -------------

    The CVOL operator performs the convolution of the LREEL2 signal 
    with the LREEL3 response. The result LREEL1 has as many points
    as LREEL2 and is implicitly associated with the same uniform
    abscissa grid of step 1.

    options :
    ---------

    - The response signal is considered to be symmetrical by default
      and LREEL3 only contains positive abscissa points. If LREEL3
      contains all the points, ENTI1 is the number of strictly negative
      abscissa points. It may be input by means of the 'NPNE' key word.
 
    - The convolution may be done by signal symmetrization or by 
      "zero padding". MOT1 can be used to specify 'SYME' or 'PADD'.
      The default is 'SYME'.
