Hello everybody, I'm totally new user of MATLAB. I have a problem about reading a text file. I have a text file which has about 9000 rows. There are strings,numerical values, characters etc. I just want to take some necessary part from the text file. I realise that the necessary par...
I would try to read the entire file in one while loop, line by line, until the end of the file is reached: % Open filesfid = fopen('test.txt');% Read Datai=1;j=1;while(~feof(fid)) line = fgetl(fid);ifstrfind(line,'.')i=i+1;continue;end; s = textscan(line,'%s','del...
Use textscan when it's possible to read multiple lines at once - it is much faster than reading a line at a time. It has many options for how to parse, which it is worth getting to know (I recommend typing doc textscan and reading the entire thing). If in doubt, ...

A.textdata = 'This is a test.' 'Start' 另外,读取的字符串只能位于数值之前,位于数值之后的将被忽略。 例:test.txt 0 1 2 1 2 1 2 3 4 End. 运行A=importdata('test.txt') 结果: A = 0 1 2 1 2 NaN 1 2 3 4 NaN NaN 除了importdata命令以外,还可以从菜单选项file-->import data......
