#### 6.1.5 Processing Data in Structures

The simplest way to process data in a structure is within a `for` loop (see Looping Over Structure Elements). A similar effect can be achieved with the `structfun` function, where a user defined function is applied to each field of the structure. See structfun.

Alternatively, to process the data in a structure, the structure might be converted to another type of container before being treated.

: c = struct2cell (s)

  Create a new cell array from the objects stored in the struct object.

  If f is the number of fields in the structure, the resulting cell array will have a dimension vector corresponding to `[f size(s)]`. For example:

      s = struct ("name", {"Peter", "Hannah", "Robert"},
                 "age", {23, 16, 3});
      c = struct2cell (s)
         ⇒ c = {2x1x3 Cell Array}
      c(1,1,:)(:)
         ⇒
            {
              [1,1] = Peter
              [2,1] = Hannah
              [3,1] = Robert
            }
      c(2,1,:)(:)
         ⇒
            {
              [1,1] = 23
              [2,1] = 16
              [3,1] = 3
            }
