Hi,
I have this cell array "baskets_data" where each cell contains a matrix that is 21 columns long.
baskets_data =
19×1 cell array
{1617×21 cell}
...
For every cell in this cell array, I want to select 9 pre-specified columns and leave out the rest. Namely, 1-3, 8-10 and 15-17.
I have written this code:
for i = 1:length(baskets_data)
baskets_xyz = baskets_data{i}(:,[1:3,8:10,15:17]);
end
But as a result I only get a baskets_xyz = 979×9 cell array.
How can I get the cell array to look as follows:
baskets_xyz =
19×1 cell array
{1617×9 cell}
...
Thank you!

Ran in:
load('baskets_data.mat');
disp(baskets_data);
{1617×21 cell} { 846×21 cell} {3812×21 cell} { 530×21 cell} {5463×21 cell} { 601×21 cell} { 998×21 cell} {1125×21 cell} { 645×21 cell} { 955×21 cell} {1747×21 cell} { 965×21 cell} { 546×21 cell} {1211×21 cell} {3023×21 cell} { 941×21 cell} { 915×21 cell} {2942×21 cell} { 979×21 cell}
baskets_xyz = cell(size(baskets_data));
for i = 1:numel(baskets_data)
baskets_xyz{i} = baskets_data{i}(:,[1:3,8:10,15:17]);
end
disp(baskets_xyz);
{1617×9 cell} { 846×9 cell} {3812×9 cell} { 530×9 cell} {5463×9 cell} { 601×9 cell} { 998×9 cell} {1125×9 cell} { 645×9 cell} { 955×9 cell} {1747×9 cell} { 965×9 cell} { 546×9 cell} {1211×9 cell} {3023×9 cell} { 941×9 cell} { 915×9 cell} {2942×9 cell} { 979×9 cell}
