matlab reads the.geo file

Hello!I have a.geo file, I want to extract all the information in it in matlab, all the Point, Line, Line Loop, Plane Surface, how can I extract the following data according to its string in matlab and convert it into a matrix。

[KSSV]

What is attached .txt file? Where is .geo file?

The.geo file cannot be uploaded, but it has the same content as the.geo file.

Here's one way:

fid = fopen('rec.txt','r');
text = fread(fid,'*char').';
fclose(fid);

data = regexp(text,'([\w ]+)\((\d+)\) = {(.+?)}','tokens');
data = vertcat(data{:});
data(:,1) = strrep(data(:,1),' ','_');
data(:,[2 3]) = cellfun(@str2num,data(:,[2 3]),'UniformOutput',false);

args = unique(data(:,1)).';
args(end+1,:) = {[]};
result = struct(args{:});

for ii = 1:size(data,1)
    result.(data{ii,1}) = subsasgn( ...
        result.(data{ii,1}), ...
        substruct('()',{data{ii,2},':'}), ...
        data{ii,3});
end

result

result = struct with fields:
             Line: [13×2 double]
        Line_Loop: [6×4 double]
    Plane_Surface: [6×1 double]
            Point: [9×4 double]
     Surface_Loop: [1 2 4 5 3 6]
           Volume: 1

result.Point

ans = 9×4

0 0 0 1 0 0 0 1 4 0 0 1 4 4 0 1 0 4 0 1 0 0 1 1 4 0 1 1 4 4 1 1 0 4 1 1

result.Line

ans = 13×2

5 1 1 3 3 4 4 5 5 9 9 6 6 7 7 7 7 8 8 9

result.Line_Loop

ans = 6×4

10 6 7 9 10 -5 -4 -13 9 13 -3 -12 5 6 11 -1 7 12 -2 -11 4 1 2 3

result.Plane_Surface

ans = 6×1

1 2 3 4 5 6
