LLM快速算法

这个程序可以将任意大的文件分割为多个任意小的文件，很好用的。-this procedure can be arbitrarily large number of documents divided arbitrarily small document, a very good use.

conpressive sensing 的MMA新程序- This is an example using the Subspace Pursuit Algorithm of Wei Dai and Olgica Milenkovic "Subspace Pursuit for Compressive Sensing: Closing the Gap Between Performance and Complexity" and the Re-weighted algorithm of Rick Chartrand and Wotao Yin "Iteratively Reweighted Algorithms for Compressive Sensing" In order to run this example you need to install all these m.files in the same directory and type trialSP2 at the prompt.

希望能帮助大家学习C语言.-hope to help you learn C language.

this code is a implementation of the Discrete cosinuss transformation. In this code I have used the direct méthode of calcul by used the equation without used the maatrix multiplication.
