现代信号处理中谱估计在matlab中的使用，是国外的成品模型，这个有中文注释，看得明白，借鉴了主成分分析算法（PCA），大学数值分析算法，在MATLAB中求图像纹理特征，PLS部分最小二乘工具箱,一种流形学习算法（很好用）。- Modern signal processing used in the spectral estimation in matlab, Foreign model is finished, The Chinese have a comment, understand it, It draws on principal component analysis algorithm (PCA), University of numerical analysis algorithms, In the MATLAB image texture feature, PLS PLS toolbox, A fluid manifold learning algorithm (good use).
