Matlab在导入过程中删除多个分隔符

Question

我正在努力解决一个问题，并希望获得简单的解决方法。我有一大堆数据，我有一些向量值（1.02 1.23 3.32）格式。我想以表格形式将它作为1.02 1.23 3.32。这里的问题是有两种类型的分隔符'（'和'）'。

任何人都可以帮忙为此编写代码吗？我有这样的事情：

filename = 'U.dat'; 
delimiterIn = '('; 
headerlinesIn = 0; 
A = textscan(filename,delimiterIn,headerlinesIn); 

但有一件事是，它只能有一个分隔符“（”和它也不管用

如果您的文本文件看起来是这样的：

(1 2 3) (4 5 6) 
(7 8 9) (10 11 12) 

你可以把它读作字符串并将其转换为向量单元阵列，像这样：

% read in file 
clear all 
filename = 'delim.txt'; 
fid = fopen(filename); %opens file for reading 
tline = fgets(fid); %reads in a line 
index = 1; 
%reads in all lines until the end of the file is reached 
while ischar(tline) 
    data{index} = tline;  
    tline = fgets(fid);   
    index = index + 1; 
end 
fclose(fid); %close file 

% convert strings to a cell array of vectors 
rowIndex = 1; 
colIndex = 1; 
outData = {}; 
innerStr = []; 

for aCell = data % for each entry in data 
    sline = aCell{1,1}; 
    for c = sline % for each charecter in the line 
     if strcmp(c, '(') 
      innerStr = []; 
     elseif strcmp(c, ')') 
      outData{rowIndex,colIndex} = num2str(innerStr); 
      colIndex = colIndex + 1; 
     else 
      innerStr = [innerStr, c]; 
     end 
    end 

    rowIndex = rowIndex + 1; 
    colIndex = 1; 
end
