Usage:

 Required Parameters:                                                  

 n1=                    number of samples in the 1st dimension          

 n2=                    number of samples in the 2nd dimenstion         

 Optional Parameters:                                                  

 error=0.01              relative RMS allowed in compress          

 Notes:                                                                

This program is used to compress a 2D section. It compresses in both

directions, vertically and horizontally.

The parameter error is used control the allowable compression error,

and thus the compression ratio. The larger the error, the more

the more compression you can get. The amount of error depends on

the type of data and the application of the compression. From my

experience, error=0.01 is a safe choice even when the compressed data

are used for further processing. For some other applications, it

may be set higher to achieve larger compression.

 Caveats:                                                               

For the current implementation, the compressed data themselves are

NOT portable, i.e., the data compressed on one platform might not be

recognizable on another.
