lpx- General linear prediction

lpx <use_first> <use_last> <predict_first> <predict_last> <coefficients> <method> <reflect> <mode>

 <use_first>     first point used to calculate the linear prediction 
                 coefficients
 <use_last>      last point used to calculate the linear prediction 
                 coefficients
 <predict_first> first data point to linear predict
 <predict_last>  last data point to linear predict
 <coefficients>  number of linear prediction coefficients used for linear 
                 predicting points    ( use: 8-16 for most data sets, 
                                        less is faster)
 <method>        method to use        ( use: 2; 3 for CT FIDs)
 <reflect>       root reflection flag ( use: 1, reduces noise)
 <mode>          mirror-image mode    ( 0 if D0=IN/2, 1 if D0=3 us)

e.g.

lpx 1 32 33 42 8 2 1 for a generic 3D spectrum ( predict 30% more points )

lpx 1 32 33 60 8 3 1 0 for a CT 3D spectrum ( predict 80% more points )
