Structures

Arrays with named fields that can contain data of varying types and sizes

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 structure using dot notation of the form structName.fieldName. For more information, see Structure Arrays or watch Introducing Structures and Cell Arrays.

Topics

Structure Arrays

Create a structure array and store data in its fields. Access the contents by name using array indexing and dot notation.
Generate Field Names from Variables
Dynamically determine a structure field name at run time from a variable or expression.
Ways to Organize Data in Structure Arrays
Consider ease of data access and system memory constraints when determining how to organize the data in a structure array.
Memory Requirements for Structure Array
Structure arrays do not require contiguous memory, but their fields do. Instead of incrementally increasing the number of fields or number of elements in a field, preallocate memory for fields containing very large arrays.
