Preallocate Memory for Cell Array
This example shows how to initialize and allocate memory for a cell array.
Cell arrays do not require completely contiguous memory. However, each cell requires contiguous
memory, as does the cell array header that MATLAB creates to describe the array. For very large
arrays, incrementally increasing the number of cells or the number of elements in a cell results in
Out of Memory errors.
Initialize a cell array by calling the cell function, or by assigning to the last element. For example,
these statements are equivalent:
C = cell(25,50);
C{25,50} = [];
MATLAB creates the header for a 25-by-50 cell array. However, MATLAB does not allocate any
memory for the contents of each cell.
