小波包分解重构matlab

在MATLAB中，进行小波包分解和重构可以使用以下代码：

t = wpdec(test_data, 3, 'db4'); % 小波包分解，3代表分解3层，'db4'表示使用db4小波
xrec = wprec(t); % 重构后的信号

这段代码使用`wpdec`函数对`test_data`进行小波包分解，其中`3`表示进行3层分解，`'db4'`表示使用db4小波。然后使用`wprec`函数对分解后的小波包进行重构，得到重构后的信号。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
