Remember that the answers are given by voluntary users in their sparetime. Then the term "as soon as possible" is not appropriate. Your question is not more urgent than the others.
You did not explain, what you call a "group". It would help to solve your problem, if you mention, what your goal is. A small example with a [6 x 3] matrix and 2 "groups" might be useful.

X = rand(2000, 512);
Y = reshape(X, 10, 200, 512);
% perhaps: Y = reshape(X, 200, 10, 512)?
% perhaps PERMUTE() such that the group index is the 3rd one?
Now you have an additional index for the group.

You did not mention yet, what a "group" is.
A [200 x 10 x 512] array can be used as "group" using the first index as "group counter".
"in this way for example y(1,:) is a one row with 5120 value which is not like what i want"
y(1,:, :) is a [10 x 512] matrix.
Please do not explain, what you do not want, but define clearly, what you do want. The readers cannot guess this detail.
