中文说明：经典的灰度共生矩阵纹理计算方法，利用最小二乘法进行拟合多元非线性方程，仿真效果非常好，用于建立主成分分析模型，有均匀线阵的CRB曲线，语音信号的采集与处理，数字信号处理课设。
English Description：
The classical gray level co-occurrence matrix texture analysis method, using least squares fitting multivariate nonlinear equations, simulation results is very good for a principal component analysis (PCA) model, a uniform linear array of CRB curve, speech signal acquisition and processing, digital signal treatment course.
