该程序（基于matlab）为小波变换在数据压缩方面的应用。原理：数据可分为高频部分和低频部分，高频部分反映了细节，而低频部分则反映概貌，故压缩部分应为高频部分。数据经此程序变换后将压缩为原来的一半。(This program (based on matlab) for the wavelet transform applications in data compression. Principle: Data can be divided into high-frequency part and low frequency, high frequency part of the reflection of the details, partly reflecting the profile of low frequency, it should be for the high frequency part of the compression part. Data will be compressed by this program change to the original half.)

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.
