如何導入這個到Matlab。我想存儲所有的數據，而不僅僅是數字。我已經嘗試過Matlab中的importdata，但是正在丟失來自對象ID和類標籤的數據。上面的數據只是一個對象，我有大約2000個這樣的對象。我想按順序存儲所有這些。

你是什麼意思「我想按順序存儲所有這些」？您可以將數據存儲在字符串的單元數組中。數據結構如下：'A {1} ='object ID：1114';''A {2} ='class label：1';'A {3} = sign含義：15-fr;'......它是否足夠將每一行存儲在一個字符串中，或者你是否期望更有意義的東西（例如，名稱對和值）？ – Rotem

該腳本打開您的文件並讀取標題和數據。

%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
