Mar 29, 2017 · data. (field_names {i}) = rand (); You can use cell2struct to construct the struct using those fieldnames and the desired values. field_names = {'num1', 'num2', 'num3'}; values = num2cell (rand (size (field_names))); S = cell2struct (values (:), field_names (:)) % num1: 0.2277 % num2: 0.4357 % num3: 0.3111.

Field names can contain ASCII letters (A–Z, a–z), digits (0–9), and underscores, and must begin with a letter. The maximum length of a field name is namelengthmax. You also can create a structure array using the struct function, described below. You can specify many fields simultaneously, or create a nonscalar structure array.
