table.getcol - Function

3.2.1 get a specific column

Description

The entire column (or part of it) is returned. Warning: it might be big! The functions can only be used if all arrays in the column have the same shape. That is guaranteed for columns containing scalars or fixed shaped arrays. For columns containing variable shaped arrays it only succeeds if all those arrays happen to have the same shape.
Note that function getvarcol can be used to get a column of arbitrary shaped arrays, which also handles empty cells correctly. Function isvarcol tells if a column contains variable shaped arrays. shaped
