matlab下实现的波束形成技术，利用的是ETAM算法进行合成孔径，增加虚拟阵元个数，以提高定位精度。(matlab achieve beam forming technology, the use of the synthetic aperture ETAM algorithm to increase the number of the virtual array elements in order to improve positioning accuracy.)

双载波的8psk调制，这是8p*2a的调制，所以是2^4进制；一个码元周期有8个载波周期；

convolution code with matlab and simulink

frft的matlab实现，可以用于数字信号处理或图像加密(these programmes are matlab realization of frft that can be used in digital signal processing or image encryption)

三个一维的matlab有限元程序，可以参考(Three one-dimensional finite element program matlab, you can refer to)

Dc-Dc converters with electrical isolation

以某些特殊函数为基将数据过程或数据系列变换为级数系列以发现它的类似频谱的特征，从而实现数据处理。(In some particular function or process the data base is converted into data series series series to discover its characteristics similar to the spectrum, to achieve data processing.)

快速的2D/3D区域生长算法，通过对邻近像素进行优先级排队进行加速，效果优于matlab本身的区域生长算法(Native Matlab implementations of region growing algorithms are usually quite slow, especially for 3D input data. This submission is a mex implementation of a 3D/2D region growing algorithm. The region growing process is further accellereated by using priority queues for the neighbourhood pixels.)
