• Signal Analyzer App: Preprocess signals by smoothing and filtering• Signal Analyzer App: Detect transients and perform time-frequency analysis usingscalogram view• One-Step Filtering: Filter signals using lowpass, highpass, bandpass, and bandstopresponses• Spectral Measurements: Kurtogram, spectral kurtosis, and spectral entropy• Rotating Machinery: Estimate and track rotational speed from vibration signals1 Signal Analyzer App
3 Kurtogram, spectral kurtosis, and spectral entropy 这几个名词之前没听说过, 信号处理果然博大精深, 等新版本出来再学吧.
计量经济学工具箱:
• Econometric Modeler App: Perform time series analysis, specification testing,
modeling, and diagnostics
编程编多了后, 就越来越喜欢用App了, 先通过App, 来 get idea, 再编程, 可以节省不少时间.
小波工具箱:
Filter Banks for Continuous Wavelet Transform: Create, visualize and use filter
banks for Time-Frequency Analysis
• Filter Banks for Discrete Wavelet Transform: Explore time-frequency characteristics
of wavelets and scaling functions
• Constant-Q Transform: Perform adaptive time-frequency analysis using
nonstationary Gabor frames
• Scalogram View: Detect transients and perform time-frequency analysis with the
Signal Analyzer App
• Empirical Mode Decomposition and Hilbert-Huang Transform: Data-adaptive timefrequency
analysis for nonlinear and nonstationary processes
• Continuous Wavelet Transform: Improved control of time-frequency parameters and
timetable support
有一个亮点: EMD分解和希尔伯特-黄变换加入了MATLAB套餐中了!
大概看了一下"Release Notes", 最让人眼前一亮的是:
• Startup: Increased speed of MATLAB startup time• Execution Engine: Execute tight loops with scalar math faster• Execution Engine: Improved performance for common programming patternsMATLAB
