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.

Create a structure array and store data in its fields. Access the contents by name using array indexing and dot notation.

- Access Elements of a Nonscalar Structure Array
- Concatenate Structures
Dynamically determine a structure field name at run time from a variable or expression.
Consider ease of data access and system memory constraints when determining how to organize the data in a 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.
This example compares cell and structure arrays and shows how to store data in each type of array. Cell and structure arrays enable you to store data of different types and sizes.
