What are cell arrays and structures?
Updated May 17, 2026
Short answer
Cell arrays store mixed datatypes, while structures organize data using named fields.
Deep explanation
Cell arrays provide flexible storage for heterogeneous data. Structures are collections of named fields that represent entities or records. Both are useful when dealing with complex or semi-structured datasets.
Real-world example
IoT systems use structures to represent sensor metadata and readings.
