对于那些使用过 jfftpack 的人,有没有办法根据从 RealDoubleFFT.ft() 命令收到的信息来计算频率?它产生一个可用于绘制 fft 的波表,但我还需要从中获取频率
private RealDoubleFFT transformer; double[] toTransform= raw data sent from short[] to the double[] transformer.ft(toTransform);
我想使用包含如下结构化代码的 jsp 页面向 ActionFormBean 发送信息:
<table> <thead> <tr> <th>ID Turno</th> <th>Data e Ora</th>
