Edit
fid=fopen('file.txt')
a=textscan(fid,'%s')
fclose(fid)
c=regexp(a{:},'\<(+|-|\.|\d)\d*(\.)?(\d+)?','match')
f=c(~cellfun(@isempty,c))
out=reshape(str2double([f{:}]'),2,[])

f = fopen('data_in_your_format.txt');
c = textscan(f,'%s','delimiter','\n');
fclose(f);
c = c{:};
[~,~,~,z] = regexp(c,'-*\d+\.\d+(e-*\d+)*');
z1 = z(~cellfun(@isempty,z));
out = str2double(reshape([z1{:}],2,[])');
