Cell Arrays

Arrays that can contain data of varying types and sizes

A cell array is a data type with indexed data containers calledcells, where each cell can contain any type of data. Cell arrays commonly contain either lists of character vectors of different lengths, or mixes of strings and numbers, or numeric arrays of different sizes. Refer to sets of cells by enclosing indices in smooth parentheses,(). Access the contents of cells by indexing with curly braces,{}. For more information, seeAccess Data in Cell Arrayor watchIntroducing Structures and Cell Arrays.

What Is a Cell Array?

A cell array is a data type with indexed data containers called cells. Each cell can contain any type of data.

Combining Cell Arrays with Non-Cell Arrays

Access Data in Cell Array

Read and write data from and to a cell array.

Pass Contents of Cell Arrays to Functions

These examples show several ways to pass data from a cell array to a function that does not recognize cell arrays as inputs.

Preallocate Memory for Cell Array

Initialize and allocate memory for a cell array.

Cell vs. Structure Arrays

This example compares cell and structure arrays, and shows how to store data in each type of array. Both cell and structure arrays allow you to store data of different types and sizes.
