File io Matlab中的文本阅读

我有一个文本文件，其中包括数字和大量的文本行。但我只需要在Matlab中将数字作为两个独立的矩阵来读取。文件如下所示：

finite element method 
Node Number
1 2 3
1 3 4
2 3 4
coordinates:
10 20
0 20
20 20
14 0

你能再清楚一点文件格式吗？行“节点编号”和“坐标：”是文件的一部分，还是有两个单独的文件？包含数字的行之间有空行吗？嗨，首先，谢谢你的关注。它们都在同一个文件中，数字之间没有空行。事实上，我的问题不知怎么解决了。我写的代码是这样的。你有更好的主意吗？？？

fid=fopen('filename.txt'); %opening the file
while ~feof(fid) %reading up to end of the file

tline = fgetl(fid); %reading line by line
if   strcmp(tline, 'Node Number') %finding the line containing " Node Number"
    break    %stop reading if the "Node Number" was detected
end
end

Nnum =transpose( fscanf(fid,'%d ' , [3 Inf])) %reading the lines after the line which we were stop
                                          % reading would stop as soon
                                          % as the format of reading
                                          % doesn't match anymore


while ~feof(fid) %continuing reading line by line again

tline = fgetl(fid);
if   strcmp(tline, 'coordinates:')%stop when the line "coordinates" 
                                  was detected
    break    
end
end

Coordinate =transpose( fscanf(fid,'%d ' , [2 Inf])) %reading lines after line
                                                "coordinate"
