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. 圖象壓縮的不同方法 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.

給定n個矩陣{A1,A2,…,An},其中Ai與Ai+1是可乘的,i=1,2,…,n-1。考察這n個矩陣的連乘積A1A2…An。由于矩陣乘法滿足結合律,故計算矩陣的連乘積可以有許多不同的計算次序,這種計算次序可以用加括號的方式來確定。若一個矩陣連乘積的計算次序完全確定,則可以依此次序反復調用2個矩陣相乘的標準算法(有改進的方法,這里不考慮)計算出矩陣連乘積。若A是一個p×q矩陣,B是一個q×r矩陣,則計算其乘積C=AB的標準算法中,需要進行pqr次數乘。
