Hi Karan, try this:
The setup:
matrix_dates = [ 1 1701 1
1702 4955 2
4956 8286 3
8287 11458 4
11459 14740 5
14741 18019 6
18020 21522 7
21523 24994 8
24995 27057 9]
inds_to_calc = [1, 2, 7, 8];
The "for-loop" way:
indices_cell = cell(size(inds_to_calc));
for i = 1:length(inds_to_calc)
from = matrix_dates(inds_to_calc(i),1);
to = matrix_dates(inds_to_calc(i),2);
indices_cell{i} = from:to;
end
all_indices = cat(2, indices_cell{:});
Or you could try the sneaky (more difficult to follow) 1-line way:
all_indices = cell2mat(arrayfun(@(from,to)from:to, matrix_dates(inds_to_calc,1), matrix_dates(inds_to_calc,2), 'UniformOutput',false)');
Either way, the answer that you wanted:
new_matrix_want = [1:1701 , 1702:4955 , 18020:21522 ,21523:24994 ]
is in the "all_indices" variable.
