how to subset table to get 2 specific columns in matlab

To subset a table in MATLAB and get two specific columns, you can use the dot indexing or the curly braces indexing.

Here's an example using dot indexing:

main.m
% Creating a sample table
tableData = table([1; 2; 3], [4; 5; 6], [7; 8; 9], 'VariableNames', {'Column1', 'Column2', 'Column3'});

% Subsetting the table to get columns 'Column1' and 'Column2'
subsetTable = tableData(:, {'Column1', 'Column2'});
245 chars
6 lines

In this example, a sample table tableData is created with three columns. The subsetTable is created by specifying the two columns 'Column1' and 'Column2' using dot indexing.

Alternatively, you can use curly braces indexing to achieve the same result:

main.m
subsetTable = tableData(:, {'Column1', 'Column2'});
52 chars
2 lines

Both approaches will result in a new table subsetTable with only the specified columns.

Make sure to replace 'Column1' and 'Column2' with the names of the columns you want to subset.
