动力缩聚后的结构刚度、质量矩阵，以及频率(Dynamic stiffness after condensation, mass matrix, and the frequency)

用流体计算李指数的。是用excel中的vba做的小程序。(calculated the lyapunov exponent)

PLS计算 Cross-Validation模型计算(PLS calculated Cross-Validation model)

说明：  常用的fluent边界条件的控制UDF，包括动网格UDF(Commonly used control UDF of fluent boundary conditions, including moving grid UDF)

傅里叶变换FFT和逆傅里叶变换IFFT 欢迎大家喜欢(FFT and IFFT)

matlab最全纹理特征代码，灰度共生矩阵软件自带，就不传了。里面有tamura六个参数，灰度梯度共生矩阵的纹理特征，还有熵。(matlab the best texture feature code, the GLCM software comes not passed. Tamura six parameters, the shades of gray co-occurrence matrix texture features, as well as entropy.)

对任意基本函数组合进行最小二乘曲线拟合的源程序。(basic function of arbitrary combinations least squares curve fitting of the source.)

说明：  阵列存在幅相误差条件下的DOA估计算法仿真(Simulation of DOA estimation algorithm with amplitude and phase errors in array)

based classification (SRC) has been widely used for face recognition (FR). SRC first codes a testing sample as a sparse linear combination of all the training samples, and then classifies the testing sample by evaluating which class leads to the minimum representation error. While the importance of sparsity is much emphasized in SRC and many related works, the use of collaborative representation (CR) in SRC is ignored by most literature.

非定常导热，附件包含3个源代码。分别对应着FTCE、BTCS和紧致格式的程序代码(unsteady conduction)
