DCT域分布式视频编码经典MMSE重建C++代码(DCT Distributed video coding tipal MMSE recostruction C++ code)

MATLAB将经纬度坐标转换成直角坐标,fsfssdgfvs(Using MATLAB latitude and longitude coordinates into Cartesian coordinates)

本代码是用四种不同的算法来实现多项式求和。(This code is used four different algorithms to achieve polynomial sum.)

In mathematics and, in particular, functional analysis, convolution is a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions. Convolution is similar to cross-correlation. (This files includes matlab source file and report file)

遗传算法是计算机科学人工智能领域中用于解决最优化的一种搜索启发式算法，是进化算法的一种。这种启发式通常用来生成有用的解决方案来优化和搜索问题。进化算法最初是借鉴了进化生物学中的一些现象而发展起来的，这些现象包括遗传、突变、自然选择以及杂交等。(In the field of artificial intelligence, a genetic algorithm (GA) is a search heuristic that mimics the process of natural selection. This heuristic (also sometimes called a metaheuristic) is routinely used to generate useful solutions to optimization and search problems.[1] Genetic algorithms belong to the larger class of evolutionary algorithms (EA), which generate solutions to optimization problems using techniques inspired by natural evolution, such as inheritance, mutation, selection, and crossover.)
