Add Cells to Cell Array

This example shows how to add cells to a cell array.

Create a 1-by-3 cell array.

C = {1, 2, 3}
C=1×3 cell
    {[1]}    {[2]}    {[3]}

Assign data to a cell outside the current dimensions. MATLAB® expands the cell array to a rectangle that includes the specified subscripts. Any intervening cells contain empty arrays.

C{4,4} = 44
C=4×4 cell
    {[       1]}    {[       2]}    {[       3]}    {0x0 double}
    {0x0 double}    {0x0 double}    {0x0 double}    {0x0 double}
    {0x0 double}    {0x0 double}    {0x0 double}    {0x0 double}
    {0x0 double}    {0x0 double}    {0x0 double}    {[      44]}

Add cells without specifying a value by assigning an empty array as the contents of a cell. C is now a 5-by-5 cell array.

C{5,5} = []
C=5×5 cell
  Columns 1 through 4

    {[       1]}    {[       2]}    {[       3]}    {0x0 double}
    {0x0 double}    {0x0 double}    {0x0 double}    {0x0 double}
    {0x0 double}    {0x0 double}    {0x0 double}    {0x0 double}
    {0x0 double}    {0x0 double}    {0x0 double}    {[      44]}
    {0x0 double}    {0x0 double}    {0x0 double}    {0x0 double}

  Column 5

    {0x0 double}
    {0x0 double}
    {0x0 double}
    {0x0 double}
    {0x0 double}
