## Probable solution...

I propose next solution:

2. Construct from input matrix large string

3. Convert string to Vector[row]

4. Import data from Vector[row]

So, as I understand the main problem consist with "parse". It works very slow.

Now my quesiton is: How to parse large string fast?

## @tomleslie I'm so sorry. I have...

This is the right one:

## My code and my file...

My code:

restart;
s := time(); L0 := ImportMatrix("D:\\HugeTest.TXT", source = delimited, delimiter = " ", datatype = float[8]); time()-s;

Thank you!

This is my result:

## @tomleslie First of all thank you f...

Now I use:

plot(L0[..,1], L0[..,2], style=pointline, symbol=point, axes = box, size = [600, 320]);

P.S. About: L0[()..()]. It is weird but if I use Ctrl+C and Ctrl+V to insert code (plot(L0[.., 1], L0[.., 2])) from Maple in my comment, I will obtain this result: plot(L0[() .. (), 1], L0[() .. (), 2]).
