Extract columns from a list of lists

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.




stats::unzipCol extracts the columns of a matrix structure encoded by a list of lists.

stats::unzipCol treats a list of lists like a list of rows of a stats::sample and extracts the columns. In conjunction with stats::sample2list it is useful for extracting the columns of a stats::sample.

stats::unzipCol is the inverse of stats::zipCol.


Example 1

We extract the columns from a list of rows representing a matrix structure:

stats::unzipCol([[a11, a12], [a21, a22], [a31, a32]])

Example 2

A list of rows is used to create a sample:

stats::sample([[123, s, 1/2], [442, s, -1/2], [322, p, -1/2]])
123  s   1/2
442  s  -1/2
322  p  -1/2

We re-convert the sample to a list of lists:


Finally, we extract the columns:




A list of lists.

Return Values

Sequence of lists to be regarded as columns.
