   > Hi @xuyang1706, thanks for your PR.
   > Could you explain the goal of the PR, please? I do not see any logic related to Flink API, also I do not see how your implementations of FFT will be work in Flink.
   > I suppose FFT should be related to Flink ML API directly, for example, FFT can implement https://github.com/apache/flink/blob/master/flink-ml-parent/flink-ml-api/src/main/java/org/apache/flink/ml/api/core/Transformer.java
   
   This is internal functions for the DCT algorithm. DCT need the implementation of Transformer,  will be summited later.
