simulink中按照相关公式建立的发动机模型(established in accordance with the relevant formula simulink engine model)

实现最小二乘法的拟合，适用于曲线的拟合，其广泛运用于当今科研等实际工作中(Implement least squares fitting curve fitting for its widely used today in practical work and scientific research)

说明：  LDPC 预编码，用于构造Raptor码(LDPC Precodes, Used to construct Raptor codes )

MDCT s program. Can be used with matlab software. Easy to compilate.

卡尔曼滤波的工程应用及源代码实现(Kalman filter engineering applications and source code)

Toeplitz 修正处理的music算法。可以提高低信噪比和低采样率下的分辨率。(Toeplitz correction algorithm processing of music. Can improve the signal to noise ratio and low resolution low sampling rates.)

Sea Water分析包主要用于海洋要素分析包括：温盐密度的计算等，是一个很好的海洋要素分析包。(seawater )

Matlab计算信噪比,单声道，双声道均可，公式准确程序清晰(Matlab calculation of signal to noise ratio, mono, dual-channel may be, the formula clear and accurate procedures)

说明：  最小均方自适应滤波器（LMS）是由Widrow和Hoff在1960年始创，它是以横向（即抽头延时线）结构为基础构建的。其最基本的形式设计简单，性能也高度高效。这两个特性使得LMS滤波器在各种应用中非常流行。递归最小二乘自适应滤波器（RLS）由于可提供快收敛速率而且对输入信号相关矩阵特征值扩散度变化不敏感，从而突破了LMS族的某些实际限制；其代价是增加了计算的复杂度。(the LMS algorithm of adaptive filter)

模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却。 (Simulated annealing algorithm derived the principle of solid annealing, heating the solid to the full high, let it slowly cooling. )
