是一个开发的小的matlab程序，自我感觉不错，和大家分享一下。(Is a development of small matlab program, self-feeling good, and everyone to share.)

the matlab fem code for some beginers .you can have a look

FDTD 的吸收边界条件讲解，详细讲解了边界条件的推导过程。(Absorbing boundary conditions for numerical simulation of waves.)

noise cancellation program

实现dtmf双音多频信号的matlab仿真编码和解码，采用coertzel算法。(Methods of measurement for pushbutton telephone with DTMF )

说明：  粒子滤波，用于对衰退数据的衰退模型的预测，同时也适用于状态跟踪 - 3(particle filter)

蚁群算法matlab实现，蚁群算法matlab实现仿真，基本功能是实现蚁群(Ant colony matlab implementation, ant colony algorithm for simulation matlab, the basic function of an ant colony)

采用FIR最小二乘逆滤波器来实现反卷积 1.通过输入信号xn与传递函数gn求输出yn 2.通过使平方误差达到最小求出最佳延迟 3通过最佳延迟求得逆滤波器传递函数hn 4通过hn与yn进行卷积运算得到还原的输入信号xn1，进行对比 5按照题设要求，进行相关噪声添加，再次进行上述实验过程 (Using least squares FIR inverse filter to achieve deconvolution)
