在matlab平台下，进行图像边缘提取的简单程序，改程序简单易懂，且实用性强，适合初学者。(In the matlab platform to carry out a simple image edge extraction process, to change procedures are simple and easy to understand, and practical, suitable for beginners.)

mais il faut connaî tre quelques extensions de syntaxe que nous allons introduire dans ce Guide d’utilisation du logiciel MATLAB

利用网格搜索法对支持向量机的参数寻优的过程，通过matlab实现(Grid search method to use SVM parameter optimization process to achieve through matlab)

Recent work by Petricoin and Liotta and co-workers (Petricoin et al. Use of proteomic patterns in serum to identify ovarian cancer. Lancet. 2002 Feb 16 359(9306):572-7. PMID: 11867112) has generated a lot of excitement and controversy. This example shows some ways that MATLAB can be used to read, visualize, pre-process (base-line correction, resample) and classify the data. The data can be downloaded from http://home.ccr.cancer.gov/ncifdaproteomics/ppatterns.asp (Recent work by Petricoin and Liotta and co-workers (Petricoin et al.
