Table: Add only selected collumns
显示 更早的评论
% Set a dummy array content:
name = {'Joe'; 'Elisa'; 'John'};
age = [30; 10; 25];
weigth = [100; 150; 180];
% Set 'select_collumns' array:
% The index (1) reference to 'name' array
% The index (2) reference to 'age' array
% The index (3) reference to 'weigth' array
selected = [1, 0, 1];
% Create a table with only select collumns: (1) Name and (3) Weigth:
How could I do it?
% Exemple:
table(name, weigth);
The main ideia is pass a 'select array' that will produce a table with only the select collumns.
How can I do it?

1. Create the full table first, however you were going to create it:
name = {'Joe'; 'Elisa'; 'John'};
age = [30; 10; 25];
weigth = [100; 150; 180]; %note that weigth is mispelled, should be weight
t = table(name, age, weight)
2. use logical indexing to select the columns you want:
selected = [1, 0, 1];
selected = logical(selected);
%or create it directly as logical:
%selected = [true, false, true];
filteredtable = t(:, selected) %only keep selected columns
