1、打开一个txt文件，会发现他既有字符又有数值。2、此时将字符全部删除，只留下有用的数据数值。3、记住该文件夹的地址，一会要作为路径用于matlab读取。4、此时使用一个textread函数，函数内部代入刚才的txt文件路径。5、textread函数会把这些数据读成1为向量。我们将其分为两列，用x和y代表，保存为...

可以在command window中输入load test.txt ,然后就会产生一个test的数据文件,内容跟test.txt中的数据一样; 另一种方法是使用窗口菜单:file/import data.../next/finish 也可产生一个叫test的数据文件。 我个人觉得用第一种方式较好。因为有些时候,特别是fx.txt 的一行种有多个数据时用load就比较麻烦了。 中英...
