Chroma Feature Analysis and Synthesis Chroma features are an interesting and powerful representation for music audio in which the entire spectrum is projected onto 12 bins representing the 12 distinct semitones (or chroma) of the musical octave. Since, in music, notes exactly one octave apart are perceived as particularly similar, knowing the distribution of chroma even without the absolute frequency (i.e. the original octave) can give useful musical information about the audio and may even reveal perceived musical similarity that is not apparent in the original spectra.

说明：  分数阶热传导工具箱可以用于求解分数阶微分方程中的热传导过程的求解，包含解析解与数值解的求解方式，含有显式，隐式和Crank–Nicolson求解方法。(The methods of solving models of heat conduction are described, namely analytical and numerical methods. In the case of numerical methods regards the finite difference method by using GL definition for the fractional time derivative. Implementation of these individual methods was realized in MATLAB. The two libraries of m-functions for the heat conduction model have been created, namely Heat Conduction Toolbox and Fractional Heat Conduction Toolbox.)
