Given a cell array C, return a cell array D with the following specifications:

1. D has the same size as the input C.

2. Each cell of D contains an empty (0x0) variable, the data type of which must match the data type of the original contents of the cell.

Examples:

1. If C = {1, 2; zeros(2, 'single'), 'ABC'} then D = { [], []; zeros(0, 'single'), ''}.

2. If C = {true, rand(2), 'MATLAB'} then D = {true(0), [], ''}.

Note: cell arrays in the test suite only contain data types present in core MATLAB.
