在matlab中将三维坐标转换成经纬度坐标或将经纬度坐标变成三维坐标(Matlab will be at three-dimensional coordinates into latitude and longitude coordinates or latitude and longitude coordinates into a three-dimensional coordinates)

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. )
