WebLike other MATLAB® arrays, a structure array can have any dimensions. A structure array has the following properties: All structures in the array have the same number of fields. All structures have the same field names. Fields of the same name in different structures can contain different types or sizes of data. WebDec 1, 2012 · There's a bunch of ways you can initialize a structure. For example, you can use the struct command: which sets all fields x to empty. You can also use deal to create and fill the structure if you know what data should go in there. xx = num2cell (1:100); [a (1:100).x]=deal (xx {:}); a (99).x ans = 99. city lights lounge in chicago
