Probabilistic Principal Components Analysis. [VAR, U, LAMBDA] = PPCA(X, PPCA_DIM) computes the principal % component subspace U of dimension PPCA_DIM using a centred covariance matrix X. The variable VAR contains the off-subspace variance (which is assumed to be spherical), while the vector LAMBDA contains the variances of each of the principal components. This is computed using the eigenvalue and eigenvector decomposition of X.

Image Compression A collection of simple routines for image compression using different techniques. 图象压缩的不同方法 BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.

给定n个矩阵{A1,A2,…,An},其中Ai与Ai+1是可乘的,i=1,2,…,n-1。考察这n个矩阵的连乘积A1A2…An。由于矩阵乘法满足结合律,故计算矩阵的连乘积可以有许多不同的计算次序,这种计算次序可以用加括号的方式来确定。若一个矩阵连乘积的计算次序完全确定,则可以依此次序反复调用2个矩阵相乘的标准算法(有改进的方法,这里不考虑)计算出矩阵连乘积。若A是一个p×q矩阵,B是一个q×r矩阵,则计算其乘积C=AB的标准算法中,需要进行pqr次数乘。
