19.07.2018 · Access a field of a nested structure, in which the structures at some levels are structure arrays. In this example, S is a 1-by-2 structure array. The second element, S(2), has a nested structure a.b, where b is a 1-by-3 structure array. First, create a nested structure.

Structure Arrays. When you have data that you want to organize by name, you can use structures to store it. Structures store data in containers called fields, which you can then access by the names you specify. Use dot notation to create, assign, and access data in structure fields. If the value stored in a field is an array, then you can use ...

s = struct (field,value) creates a structure array with the specified field and value. The value input argument can be any data type, such as a numeric, logical, character, or cell array. If value is not a cell array, or if value is a scalar cell array, then s is a scalar structure. For instance, s = struct ('a', [1 2 3]) creates a 1-by-1 ...

If the value stored in a field is an array, then you can use array indexing to access elements of the array. When you store ...

Access Elements of a Nonscalar Structure Array. This example shows how to access and process data from multiple elements of a nonscalar structure array: Create a 1-by-3 structure s with field f: s (1).f = 1; s (2).f = 'two' ; s (3).f = 3 * ones (3); Although each structure in the array must have the same number of fields and the same field ...

A structure array is a data type that groups related data using data containers called fields. Each field can contain any type of data. Access data in a ...

Mar 29, 2017 · If you create your structure using numeric arrays instead of cell arrays, like so: A = struct ('a1', [1 2 3],'a2', [4 5 6]); Then you can access the value of 1 as follows: A.a1 (1) For further information about working with structures in MATLAB, check out this documentation page. Share.

It shouldn't be a problem with what you've shown since every structure in the structure array has a unique value for the symbol field. If you have a situation where the same symbol could appear in multiple strcutures in the array, I suggest you look into ismember() to pull out only those structures in the array where the symbol field has the symbol you're looking to extract.
