The flatten command
replaces any sublists of a list by their elements.
flatten takes
L, a list.
flatten(L) returns a list which is the result of
recursively replacing any elements that are lists by the elements,
resulting in a list with no lists as elements.
Example
flatten([[1,[2,3],4],[5,6]])
⎡
⎣
1,2,3,4,5,6
⎤
⎦
Remark.
If the original list is a matrix, you can also use the mat2list
command for this (see Section 6.3.33).
