说明：  这是初学者学习Matlab的经典课件，第一到五章，包含微积分问题、线性代数问题以及数据拟合方法等(This is the classic beginner learning courseware Matlab, first to the five chapters, including the issue of calculus, linear algebra problems, and data fitting methods)

介绍bpsk调制的一个比较完整的系统，系统内有误码率的处理，时域和频域之间的转换(introduce bpsk modulation)

用神经网络进行训练和仿真的接口函数，用matlab编写，适合进行这方面的仿真开发．(using neural network training and simulation interface function, Matlab preparation, suitable for the simulation of this development.)

DMI 矩阵逆分解 随期望信号的增大的算法估计的变化(DMI matrix inverse decomposition increases with the expected signal changes in the algorithm estimates)

能将日常生活中拍照不小心带来的红眼DAI而给图片造成不美的麻烦给消除掉了。(Photos in daily life can be careless red-eye DAI brought to the picture caused by the United States trouble eliminated . )

说明：  插值，只用于精确的数据，因为通过指定的准确点拟合曲线。这个算法很有用，通过几个给定的点来绘制平滑曲线。(Use only for precise data, as the fitted curve passes through the given points exactly. This routine is useful for plotting a pleasingly smooth curve through a few given points for purposes of plotting.)

自己写的几个小程序，包括冲激函数，阶跃函数，时域采样，恢复，内插等程序。很好用。(Write several small programs, including the impulse function, step function, time domain sampling, recovery, interpolation procedures. Good use.)

说明：  三点二次插值的matlab程序和0.618法的matlab程序，(Three-point quadratic interpolation matlab matlab law procedures and procedures 0.618,)

自适应滤波算法的matlab程序，音频去噪(Adaptive filtering algorithm matlab program, Audio Clean)
