MATLAB empty cell (n, m) array of strings?

Question

What is the fastest way to create an empty array of row cells?

cell(n,m) 

creates an empty array of double cells.

How about a similar command, but creating empty lines?

Answer 1

Depends on what you really want to achieve. I think the easiest way:

 repmat({''},n,m); 

Answer 2

Assigning all the elements of the cell using the colon operator will complete the task:

 m = 3; n = 5; C = cell(m,n); C(:) = {''} 

Answer 3

The cell cell created by cell (n, m) contains empty matrices, not doubles. If you really need to pre-populate the cell array with blank lines

 test = cell(n,m); test(:) = {''}; test(1,:) = {'1st row'}; test(:,1) = {'1st col'};
