- Function File: extractfield
(s, field)¶ Extract field values from struct array.
Concatenates all the values from the field member field in the structure array s. The values are all concatenated into a row vector of the same type as the values.
s(1).field = 1:3; s(2).field = 4:9; extractfield (s, "field") ⇒ [ 1 2 3 4 5 6 7 8 9 ]
If any of the values is a string, or if the class is not the same for all the elements, a cell array with the intact elements is returned instead.
s(1).field = 1:3; s(2).field = uint8 (4:6); extractfield (s, "field") ⇒ [ 1 2 3 ] ⇒ [ 4 5 6 ]
s(1).field = "text"; s(2).field = 1:3; extractfield (s, "field") ⇒ text ⇒ [ 1 2 3 ]
