Delete Data from a Cell Array

This example shows how to remove data from individual cells, and how to delete entire cells from a cell array. To run the code in this example, create a 3-by-3 cell array:

C = {1, 2, 3; 4, 5, 6; 7, 8, 9};

Delete the contents of a particular cell by assigning an empty array to the cell, using curly braces for content indexing, {}:

C{2,2} = []

This code returns

C = 
    [1]    [2]    [3]
    [4]     []    [6]
    [7]    [8]    [9]

Delete sets of cells using standard array indexing with smooth parentheses, (). For example, this command

C(2,:) = []

removes the second row of C:

C = 
    [1]    [2]    [3]
    [7]    [8]    [9]
