如何进行文本扫描以读取文件中的所有行 [英] how to textscan to read all the lines in a file

问题描述

我正在尝试使用以下

file_content = textscan(fid, '%s', 'delimiter', '\n', 'whitespace', '')

但这只会返回

file_content = 

    {0x1 cell}

实际上我的文件有224行.因此，如果我使用

when actually my file has 224 line. so if i use

file_content = textscan(fid,'%s',224,'delimiter','\n')

我了解所有情况

file_content = 

    {224x1 cell}

什么是读取.m文件中所有数据(主要是字符串)的更合适方法? 谢谢

what will be a more proper way to read all the data(mostly strings) in a .m file? thanks

推荐答案

由于您没有列出您的需要(您正在阅读一个大文件吗?许多小文件吗?速度是一个问题吗?您真正想要做什么? )我给你最简单的答案:

Since you do not list your needs (are you reading a huge file?, many small files? is speed an issue? what do you really want to do?) I'm giving you the simplest possible answer:

您这样做:

f = fopen('data.txt');             
g = textscan(f,'%s','delimiter','\n');
fclose(f);

请记住在阅读后关闭，否则您将无法再次阅读.

remember to close after reading, because otherwise you won't be able to read again.

您可以将第一行作为g {1} {1}，将第二行作为g {1} {2}，依此类推.

You can get the first line as g{1}{1}, the second as g{1}{2} and so on.

这是 textscan 的matlab文档，其中提供了更多内容详细信息.

Here is the matlab documentation for textscan which gives a lot more details.
