MATLAB中怎么把从外界导入数组，并且要删除其中的英文字符，只保留数据？？？

数组

从以上数组中选取，最好能做到只有第三列第五列第十列组成的数组。麻烦各位了~~~~~

Answer 1

将文本复制到txt文本中，注意每一行的格式要相同，将所有的，和,换成辩或销空格键，用全部替换就可以做到，假设以data命名，保存在E盘上，
输入以下程序：
[str1 str2 str3]=textread('E:\data.txt','%*s%*s%f%*s%f%*s%*s%*s%*s%f%*s%*s%*s%*s%*s')
'E:\data.txt'根据自己存放data.txt更改路径，
这样第携游3,5,10列数据就分别保存在str1，str2，str3里面了团塌
如果想要显示长数据，在上面的程序前面加上
format long

>> [str1 str2 str3]
ans =
1.0e+004 *
