MIT--航空航天工程中的计算方法_最优化方案 MIT公开课程--航空航天工程中的计算方法 这门课程适用于在航空和航天工程中出现的计算方法的入门学习。其应用是从航空宇宙结构，空气动力学，动力学和控制，和航空宇宙系统选出的。其技术包括：常微分方程系统的数值积分；偏微分方程式的有限差分,有限体积, 和有限元的离散化；数值线性代数；本征值问题和带有约束的最优化。 (MIT- Aerospace engineering calculations _ MIT open course program optimization- Aerospace engineering calculation methods for this course in aviation and aerospace engineering calculations appear in an introduction. The application is from aerospace structures, aerodynamics, dynamics and control, and aerospace systems selected. The technologies include: numerical integration of ordinary differential equations systems partial differential equations of finite difference, finite volume, and finite element discretization numerical linear algebra eigenvalue problems with constraints and optimization.)

说明：  主动声呐匹配场计算程序matlab程序包(Calculation program of active sonar matching field)

说明：  认知条件下干扰问题的优化，次用户对于主用户的干扰尽量减小(Cognitive interference under the conditions optimized for secondary users to minimize interference with primary users)

横向各相同性介质的各个弹性系数，方便进一步计算其它弹性性质(the elastic properties of TI media)

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)

说明：  costas环基于matlab的simulink的仿真实现(costas loop in simulink matlab-based simulation to achieve)

非常实用的小波包分解程序，以及实现对小波包分解频带求取频谱和能量谱(Very useful wavelet packet decomposition process, and the realization of the wavelet packet decomposition to obtain the spectrum and the energy spectrum band)

好用的matlab程序，专门针对冲激串的傅立叶变换设计的(welldone，good things to learn matlab)

Descriptor for simple shapes (e.g letters). Computes the descriptor twice in order to describe horizontally and vertically with the same accuracy. Input: image (2-D, binary or gray) depth of recursion (default 7), plotFlag(if on - plot Illustration) Output: vec - descriptor: Division locations, values around zero. Of length 2*(2^depth - 2) (levels: the depth of the division locations.)

仿真一个从卫星到区域数据中心的下行链路（由一组6个载波构成），评估热噪声，交调（IM）失真、由滤波器引起的码间干扰（ISI）以及临频干扰对下行链路性能的影响。(Simulation of a regional data center from the satellite to the downlink (from a group of six carrier composition) to assess the thermal noise, intermodulation (IM) distortion, caused by the filter ISI (ISI) and adjacent channel interference on the downlink link performance.)
