Nesting Cell Arrays
A cell can contain another cell array, or even an array of cell arrays. (Cells that contain noncell data are called leaf cells.) You can use nested curly braces, the
function, or direct assignment statements to create nested cell arrays. You can then access and manipulate individual cells, subarrays of cells, or cell elements.
Building Nested Arrays with Nested Curly Braces
You can nest pairs of curly braces to create a nested cell array. For example,
Note that the right side of the assignment is enclosed in two sets of curly braces. The first set represents cell
(1,2) of cell array
A. The second "packages" the 2-by-2 cell array inside the outer cell.
Building Nested Arrays with the cell Function
To nest cell arrays with the
cell function, assign the output of
cell to an existing cell:
A, including the nested array, using assignments.
You can also build nested cell arrays with direct assignments using the statements shown in step 3 above.
Indexing Nested Cell Arrays
To index nested cells, concatenate indexing expressions. The first set of subscripts accesses the top layer of cells, and subsequent sets of parentheses access successively deeper layers.
For example, array
A has three levels of nesting:
