In MATLAB, a structure array is a data type that groups related data into fields, where each field can store any type of data — numeric, text, logical, cell arrays, or even other structures. Fields are accessed using dot notation like structName.fieldName.
Creating Structures can be done in multiple ways:
Dot notation:
data.x = linspace(0, 2*pi);data.y = sin(data.x);data.title = 'y = sin(x)';Copied!✕CopyUsing struct() function:
s = struct('Name', {'Riya', 'Tiya', 'Siya'}, 'Age', [20, 22, 19]);Copied!✕CopyIf values are cell arrays, MATLAB creates a non-scalar structure array with matching dimensions.
Accessing and Modifying Fields:
% Accessages = s.Age;% Modifys(1).Age = 21;% Add new fields(1).Grade = 'A';Copied!✕CopyEmpty and Nested Structures:
% Empty structure with fieldss = struct('a', {}, 'b', {}, 'c', {});% Nested structurea.b = struct('c', {}, 'd', {});Copied!✕CopyBuilt-in Functions for Structures:
