我正在尝试读取具有以下重复格式的文件(但由于数据太长,即使是第一次重复,我也已经删除了数据):
1.00 'day' 2011-01-02
'Total Velocity Magnitude RC - Matrix' 'm/day'
0.190189 0.279141 0.452853 0.61355 0.757833 0.884577
0.994502 1.08952 1.17203 1.24442 1.30872 1.36653
1.41897 1.46675 1.51035 1.55003 1.58595 1.61824
在此处下载包含完整数据的实际文件
这是我用来从上述文件中读取数据的代码:
fid = fopen(file_name); % open the file
dotTXT_fileContents = textscan(fid,'%s','Delimiter','\n'); % read it as string ('%s') into one big array, row by row
dotTXT_fileContents = dotTXT_fileContents{1};
fclose(fid); %# don't forget to close the file again
%# find rows containing 'Total Velocity Magnitude RC - Matrix' 'm/day'
data_starts = strmatch('''Total Velocity Magnitude RC - Matrix'' ''m/day''',...
dotTXT_fileContents); % data_starts contains the line numbers wherever 'Total Velocity Magnitude RC - Matrix' 'm/day' is found
ndata = length(data_starts); % total no. of data values will be equal to the corresponding no. of '** K' read from the .txt file
%# loop through the file and read the numeric data
for w = 1:ndata-1
%# read lines containing numbers
tmp_str = dotTXT_fileContents(data_starts(w)+1:data_starts(w+1)-3); % stores the content from file dotTXT_fileContents of the rows following the row containing 'Total Velocity Magnitude RC - Matrix' 'm/day' in form of string
%# convert strings to numbers
tmp_str = tmp_str{:}; % store the content of the string which contains data in form of a character
%# assign output
data_matrix_grid_wise(w,:) = str2num(tmp_str); % convert the part of the character containing data into number
end
为了让您了解我的文本文件中的数据模式,以下是代码的一些结果:
data_starts =
2
1672
3342
5012
6682
8352
10022
ndata =
7
因此,我的data_matrix_grid_wise
应该包含1672-2-2-1(for a new line)=1667
行。但是,我得到了这个结果:
data_matrix_grid_wise =

我哪里错了?在我的最终结果中,我应该data_matrix_grid_wise
由10000
元素而不是36
元素组成。谢谢。
更新:如何在 data_starts(w) 之前的一行中包含“day”之前的数字,即 1、2、3 等?我在循环中使用它,但它似乎不起作用:
days_str = dotTXT_fileContents(data_starts(w)-1);
days_str = days_str{1};
days(w,:) = sscanf(days_str(w-1,:), '%d %*s %*s', [1, inf]);
