Cell

You can use the cell function, for example: C = cell(3,4,2) OR you can use the {} operator, for example: C{3,4,2} = [ ]. Both methods produce a cell array with each cell containing an empty, 0-by-0 array of type double.

Creating cell arrays in MATLAB is similar to creating arrays of other MATLAB data types like double, character, etc. The main difference is that, when constructing a cell array, you enclose the array contents or indices with curly braces { } instead of square brackets [ ]. The curly braces are cell array constructors, just as square brackets are numeric array constructors. Use commas or spaces to separate elements and semicolons to terminate each row. For example, to create a 2-by-2 cell array A, type A = {[1 4 3; 0 5 8; 7 2 9], 'Anne Smith'; 3+7i, -pi:pi/4:pi};
