#### 6.4.2 Comma-Separated Lists Generated from Structure Arrays ¶

Structure arrays can equally be used to create comma-separated lists. This is done by addressing one of the fields of a structure array. For example:

    x = ceil (randn (10, 1));
    in = struct ("call1", {x, 3, "last"},
                 "call2", {x, inf, "first"});
    out = struct ("call1", cell (2, 1), "call2", cell (2, 1));
    [out.call1] = find (in.call1);
    [out.call2] = find (in.call2);
