如何将其导入Matlab。我想存储所有的数据，而不仅仅是数字。我曾尝试在Matlab中导入数据，但丢失了来自对象id和类标签的数据。上面的数据只是一个对象，我有大约2000个这样的对象。我想按顺序存储所有这些内容。

此脚本打开文件并读取标题和数据

%Open file as text
fid=fopen('filename.txt','rt');

%First read the header information
l='';
header=struct;
l=fgetl(fid);
while ~strcmp(l,'trajectory:')
    s=regexp(l,':','split');
    s{1}=regexprep(s{1},' |-','_'); %remove spaces from header names
    if length(s)==2
        header.(s{1})=s{2};
    end
    l=fgetl(fid);
end

%then read data
data=[];
l=fgetl(fid);
while ~isnumeric(l)
    data(end+1,:)=str2num(l);
    l=fgetl(fid);
end
fclose(fid);
clear s l fid

“我想按顺序存储所有这些”是什么意思？您可以将数据存储在字符串的单元格数组中。数据结构看起来像：

A{1}='objectid:1114'
A{2}='类标签：1'
A{3}=符号含义：15 fr。。。将每一行存储在一个字符串中是否足够，或者您是否希望得到更有意义的内容（例如名称和值对）？
