对一维信号采样并进行傅里叶变换画出频谱图。(Sampling and Fourier transform draw spectrum diagram of one-dimensional signal.)

disizhangchegnxu程序集合是北京航空航天大学编写的(disizhangchegnxu collection procedure is to write the Beijing University of Aeronautics and Astronautics)

用于对全景镜头进行标定，能求解出图像上对应点的世界坐标的方向向量(The OcamCalib Toolbox for Matlab allows the user (also inexpert users) to calibrate any central omnidirectional camera, that is, any panoramic camera having a single effective viewpoint (see section 17). The Toolbox implements the procedure initially described in the paper(Scaramuzza, D., Martinelli, A. and Siegwart, R., (2006). "A Flexible Technique for Accurate Omnidirectional Camera Calibration and Structure from Motion", Proceedings of IEEE International Conference of Vision Systems (ICVS 06), New York, January 5-7, 2006.) and later extended in (Scaramuzza, D., Martinelli, A. and Siegwart, R., (2006). "A Toolbox for Easy Calibrating Omnidirectional Cameras", Proceedings to IEEE International Conference on Intelligent Robots and Systems (IROS 2006), Beijing China, October 7-15, 2006. ). A detailed introduction to this model is in section 19 of this Tutorial. Furthermore, you can also see a demo of how the toolbox works here. The Toolbox permits the user to easily and quickly cal)

arma模型的matlab实现，亲测可用，可以求出p.q阶数(arma matlab)

三维时域有限差分matlab程序，带完美匹配层(Three-dimensional finite-difference time-domain matlab program, with perfectly matched layer)

发电公司一般不允许改变当天的电价投标,但可以改变机组的可用性.因此,在获得发电量之后如何组织机组进行发电,同时,又要保证成本低、效益高、收益大,是每个发电公司需要解决的问题,而行之有效的方法就是动态规划。(Power companies generally are not allowed to change the electricity price bidding, but can change the usability of the unit. Therefore, how to organize the unit after obtaining her capacity to generate power, at the same time, and to ensure that the low cost, high efficiency, large gains, is each generation company needs to solve the problem, and the effective method of dynamic planning.)

the code uses cma for channel identification and equalization

A novel algorithm for sparse approximation in redundant dictionaries, called the M-Term Pursuit (MTP). This algorithm decomposes a signal into a linear combination of atoms that are selected in order to represent the main signal components.
