m_PN
说明： 伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。从波形上看，原有信号完全淹没于随机的噪声中，达到隐藏信号和抗干扰的目的。接受方只要有相同的伪随机序列，就可以通过伪随机序列很强的相关性将信号还原出来。而m序列，是扩频系统中最长用的伪随机序列。下面的代码就是基于matlab的生成m序列的代码，通过改变初始多项式的值，就可以生成不同阶数的m序列。(Pseudo-random code or PN code, spread spectrum communication is indispensable to a sequence. Spread spectrum communication, a simple to say that the adoption of a group of highly related to pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence there. From the wave point of view, the original signal completely submerged in the random noise to hide the purpose of signal and interference. As long as the recipient has the same pseudo-random sequence, the pseudo-random sequence can be a strong correlation to restore the signal out. And m sequence spread spectrum system is the longest of the pseudo-random sequence used. The following code is generated based on m sequences of matlab code, by changing the value of the initial polynomial, we can generate a different order of the m sequence.)

Hpoz_txt2coord
使用此函数来提取一个地理坐标输入字符串了。该功能非常灵活，因此，协调可能位于任何地方的字符串，并可能有许多的格式之一。
例子：
txt2coord（ 100 ° 7 30“宽 ）
txt2coord（ 100 ° 7 30 w 的）
txt2coord（ -100 ° 7 30“ ）
txt2coord（ 100 ° 75 w 的）
txt2coord（ 100 .125 °以西 ）
txt2coord（ 喇嘛100 °，7分钟 30 S喇嘛 ）
txt2coord（{ 100 .125 ° w 的 -100.125 ° }）
所有指定的例子得出正确的结果（-100.125）。
我已经成功测试了多种不同的投入这一点。然而，正则表达式，这是在该文件中使用广泛，...嗯...他们有时有一个有趣的方式展示你，你没有带他们出去尚未完全想通。因此，我强烈建议你使用它之前的一些performe此功能完整性检查和将不胜感激，如果你向我报告任何错误。
(Use this function to extract one geographical coordinate out of an input string. The function is extremely flexible, thus the coordinate may be located anywhere in the string and may have one of many formats.
Examples:
txt2coord( 100° 7 30" W )
txt2coord( 100° 7´ 30´ ´ W )
txt2coord( -100° 7` 30" )
txt2coord( 100° 7.5 W )
txt2coord( 100.125° west )
txt2coord( bla 100°, 7min 30´ ´ S bla )
txt2coord({ 100.125° W -100.125° })
All specified examples yield the correct result (-100.125).
I have successfully tested this with various inputs. Yet, regular expressions, which are extensively used in this file, ... well ... they sometimes have a funny way of showing you that you havn t quite figured them out yet. Therefore, I would strongly advice you to performe some sanity-check on this function before using it and would be greatful, if you report any bugs to me.
