REC1D/WAVE  Wave_in Im_out [Num_Trans] [Channel] [Nu0]
	
\us\pu
Purpose:    
            reconstructs a signal from its wavelet transform
\up\sy
Syntax:     
            REC1D/WAVE Wave_in Im_out [Num_Trans] [Channel] [Nu0]
\ys\pa
            Wave_in = input wavelet transform. The wavelet transform of
                   a one dimensional signal is an image.
\ap\pa
            Im_Out =  image file name of the reconstructed signal
                   this image has only one line.
\ap\pa
            Num_Trans = algorithm which has been used to compute 
                   the wavelet transform. 6 transforms are possible:
                        1: french hat\\
                        2: mexican hat\\
                        3: a trous algorithm with a linear scaling function\\
                        4: a trous algorithm with B1-spline scaling function\\
                        5: a trous algorithm with B3-spline scaling function\\
                        6: Morlet's transform\\
                   In the case of Morlet's transform, the wavelet transform
                   is complex. The modulus of the transform must tored in the
                   first part of the output image, and the phase in the second
                   part. Default value is 2.
\ap\pa
            Channel = number of channel per octave; the default value is 12.
                   this parameter is not used in the a-trous algorithm because
                   a-trous algorithm is a diadic algorithm (1 channel per octa)
\ap\pa
            Nu =   Morlet's parameter; only used with Morlet's transform

Note:       
            The reconstruction parameters must be the same as the wavelet 
            transform parameters. Morlet's reconstruction is not implemented.

Examples:
\ex
            REC1D/WAVE transform sig_rec
            reconstructs the signal from its wavelet transform. The result
            is stored in the file "sig_rec"
