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,[])

Thank you so much

Answer 2

[Andrei Bobrov]

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,[])');

Thank you code 2 works perfectly if the numbers are positive but if numbers are negative it doesn't work. Is there some modification to be done? If the numbers are mix of positives and negatives
