我的数据采用以下格式:

TABLE NUMBER 1
                                                FILE: name_1
                                                            name_2

6573.99 28489.7 
6938.99 28244.2 
7304.99 28012.9 
TABLE NUMBER 3

到目前为止,我正在分割这些数据并按以下方式从每个文件中读取变量(时间和name_i)

[TIME(:,j), name_i(:,j)]=textread('filename','%f\t%f','headerlines',5);

但现在我正在将这些文件的数据生成到1个文件中如开头所示。例如,我想分别为 name_3、name_6、_9 读取和存储向量 TIME1、TIME2、TIME3、TIME4、TIME5 中的时间数据,对于其他数据也类似。

My data is in following format:

TABLE NUMBER 1
                                                FILE: name_1
                                                            name_2

TABLE NUMBER 3

Till now I was splitting this data and reading the variables (time and name_i) from each file in following way:

[TIME(:,j), name_i(:,j)]=textread('filename','%f\t%f','headerlines',5);

But now I am producing the data of those files into 1 file as shown in beginning. For example I want to read and store TIME data in vectors TIME1, TIME2, TIME3, TIME4, TIME5 for name_3, name_6, _9 respectively, and similarly for others.

首先,我建议您不要使用诸如 TIME1、TIME2 等变量名称,因为这很快就会变得混乱。相反,您可以使用具有五行(每孔一行)和一列或两列的单元阵列。在下面的示例代码中,wellData{2,1} 是第二口井的时间,wellData{2,2} 是相应的石油费率 SC - 年。

可能有更优雅的方式来进行阅读;这是一些快速的事情:

%# open the file
fid = fopen('Reportq.rwo');

%# read it into one big array, row by row
fileContents = textscan(fid,'%s','Delimiter','\n');
fileContents = fileContents{1};
fclose(fid); %# don't forget to close the file again

%# find rows containing TABLE NUMBER
wellStarts = strmatch('TABLE NUMBER',fileContents);
nWells = length(wellStarts);

%# loop through the wells and read the numeric data
wellData = cell(nWells,2);
wellStarts = [wellStarts;length(fileContents)];

for w = 1:nWells 
    %# read lines containing numbers
    tmp = fileContents(wellStarts(w)+5:wellStarts(w+1)-1);
    %# convert strings to numbers
    tmp = cellfun(@str2num,tmp,'uniformOutput',false);
    %# catenate array
    tmp = cat(1,tmp{:});
    %# assign output
    wellData(w,:) = mat2cell(tmp,size(tmp,1),[1,1]);
end

First of all, I suggest you don't use variable names such as TIME1,TIME2 etc, since that gets messy quickly. Instead, you can e.g. use a cell array with five rows (one for each well), and one or two columns. In the sample code below, wellData{2,1} is the time for the second well, wellData{2,2} is the corresponding Oil Rate SC - Yearly.

There might be more elegant ways to do the reading; here's something quick:

%# open the file
fid = fopen('Reportq.rwo');

%# read it into one big array, row by row
fileContents = textscan(fid,'%s','Delimiter','\n');
fileContents = fileContents{1};
fclose(fid); %# don't forget to close the file again

%# find rows containing TABLE NUMBER
wellStarts = strmatch('TABLE NUMBER',fileContents);
nWells = length(wellStarts);

%# loop through the wells and read the numeric data
wellData = cell(nWells,2);
wellStarts = [wellStarts;length(fileContents)];

for w = 1:nWells 
    %# read lines containing numbers
    tmp = fileContents(wellStarts(w)+5:wellStarts(w+1)-1);
    %# convert strings to numbers
    tmp = cellfun(@str2num,tmp,'uniformOutput',false);
    %# catenate array
    tmp = cat(1,tmp{:});
    %# assign output
    wellData(w,:) = mat2cell(tmp,size(tmp,1),[1,1]);
