datasheet(48*6)size
%I had a matrix of size(48*6) and then
ii = randperm(size(datasheet,1));
k = ones(24,1)*2;
out = mat2cell(datasheet(ii(1:sum(k)),:),k,size(datasheet,2));
%then i select a row from datasheet lets say 4th row
B=datasheet(4,:);
%now I want to find out the position of that 4th row in "out" matrix.

In general case:
[~,ji] = cellfun(@(x)ismember(B,x,'rows'),out,'un',0);
jj_cell = find(cellfun(@(x)x>0,ji));
ii_row_in_cell = ji{jj_cell};
