Hi, there
I got a time-series data array (suppose array X ), Now I want to use
wavelet functions in IDL library to filter the array, so that I can
remove the abnormal data elements and make the time-series data more
reasonable.

Which functions should I use?

In fact, I check some methods like WV_FN_COIFLET, or WV_DENOISE, but
it dose not work, and the online help has no examples about this
parts. So, I will be appreciate if you can give me an example. Many
thanks.
