Timing Decomposition | MATLAB Realizes Visualization of Signal Decomposition Components Based on LMD Local Mean Decomposition
Table of contents
Effect list
basic introduction
LMD local mean decomposition can directly replace Excel and run Matlab language including spectrogram and correlation coefficient diagram
1. The algorithm is novel and niche, and few people use it. It includes decomposition diagram, spectrogram, and correlation coefficient diagram. The effect is as shown in the figure. It is suitable as Create❤️~
2. Directly replace the Excel data and use it. Suitable for novices and clear annotations~
3. Comes with test data and run main directly to generate graphs with one click~
