You can write your own import function using fopen:
Assuming your data looks something like this:
Comments
2.35 93.1 294.1 593.1
23.1 345.4 127812947.12834 1282881.1
Then:
A = zeros(100000, 101); % This is ~ 800MB, are you sure you have enough memory?
fid = fopen('data.txt', 'r');
row = 1;
% Skip first line
tline = fgetl(fid);
while 1
tline = fgetl(fid);
if ~ischar(tline), break, end
A(row, :) = str2double(regexp(tline, ' ', 'split'));
end
fclose(fid);
If you have binary data, use fread instead.
Good luck.
