polarPcolor
polarPcolor是一个函数,旨在用极坐标表示伪彩色图,与径向网格允许数据的一个简单的演讲。它非常适合平面位置显示器(PPI)扫描雷达为例。我们的目标是提供信息的极坐标给定变量Z。(polarPcolor is a function that aims to represent a pseudocolor plot in polar coordinates, with a radial grid to allow an easy lecture of the data. It is well suited for Plan Position Indicator (PPI) scan for radar for example. The goal is to provide information about the polar coordinate of a given variable Z. )

Matlab版俄罗斯方块，个人一直认为，这个游戏或者说这个程序很经典！如果你能掌握这个程序，你对Matlab的外功已经不成问题，回家修炼一下内功，就能毕业了！！不说别的，先来玩玩，别忘了把音箱打开！感受儿时的乐趣程序作者：Pascal Getreuer (Matlab version of Tetris, individuals have always thought that this game or that the program was classic! If you can master this program, you have no problem Matlab' s external work, home practice about internal strength, we can graduate! ! If nothing else, the first to play, do not forget to turn on speakers! Experience the fun process of childhood: Pascal Getreuer)
