MATLAB: Determining fscanf formatspec.

formatspec fscanffscanfMATLAB

Hi, i'm trying to make [n , 4] table with the a.txt
I need only need numeric datas but i have no idea which formatSpec i need to use.
I have no idea how to deal with the space blanks between numbers i need.
a = fopen('a.txt' ,'r')
data = fscanf(a , FromatSpec , [4 inf])
Please let me which Formatspec could make them to the matrix i need.
I want to use fscanf.

Try this code using fscanf()
lines = strsplit(fileread('a.txt'), '\n', 'CollapseDelimiters', false);
idx = find(contains(lines, 'Global Statistics'));
idx = [9 idx+10];
data = cell(1, numel(idx));
fid = fopen('a.txt' ,'r');
line_read = 0;
for i = 1:numel(idx)
    nls = idx(i)-line_read;
    arrayfun(@(x) {fgetl(fid)}, 1:nls);
    data{i} = fscanf(fid , '%f %f %f %f', [4, inf]).';
    line_read = idx(i) + size(data{i},1)+1;
end
fclose(fid);
idx = cellfun(@isempty, data);
data(idx) = [];
