读入指定的音频序列，并对其进行无损预测编码和DM调制编码(Read into the specified audio sequences, and its lossless predictive coding and modulation coding DM)

curvelet变换matlab程序和c程序(curvelet transform)

利用MATLAB实现峰值信噪噪比的公式，很好用。精确的验证过 (Using MATLAB to achieve a peak signal-to-noise to noise ratio formula, easy to use. Verified accurate)

线性规划问题，用两阶段法求解。输入输出的类型均为有理数，每个有理数用两个长整形表示。(Linear programming problem, using a two-stage method to solve. The type of input and output are rational, every rational number indicated by two long plastic surgery.)
