Combine 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.


zip(list1, list2, f)
zip(list1, list2, f, default)


zip(list1, list2, f) combines two lists via a function f. It returns a list whose i-th entry is f(list1[i], list2[i]). Its length is the minimum of the lengths of the two input lists.

zip(list1, list2, f, default) returns a list whose length is the maximum of the lengths of the two input lists. The shorter list is padded with the default value.

If f produces the void object of type DOM_NULL, then this element is removed from the resulting list.

zip is recommended for fast manipulation of lists. It is a function of the system kernel.


Example 1

The fastest way of adding the entries of two lists is to 'zip' them via the function _plus:

zip([a, b, c, d], [1, 2, 3, 4], _plus)

If the input lists have different lengths, then the shorter list determines the length of the returned list:

zip([a, b, c, d], [1, 2], _plus)

The longer list determines the length of the returned list if a value for padding the shorter list is provided:

zip([a, b, c, d], [1, 2], _plus, 17)
