cell automatically convers into cell array in matlab

In MATLAB, you can automatically convert a cell to a cell array by enclosing it with curly braces {}. Here's an example:

main.m
a = cell(1, 3); % create an empty cell
a{1} = 'apple';
a{2} = 1:3;
a{3} = rand(2, 3);
86 chars
5 lines

Here, a is a 1-by-3 cell array where each cell contains a different type of data (char array, double array, and a matrix of random numbers).

To automatically convert a into a cell array, we simply wrap it with curly braces:

main.m
b = {a};
9 chars
2 lines

b is now a 1-by-1 cell array that contains the original cell a.

You can also use this technique to convert other data types to cell arrays, like matrices or structs:

main.m
% convert a matrix
M = magic(3);
cellM = {M};

% convert a struct
S = struct('name', {'Alice', 'Bob', 'Charlie'}, 'age', [25, 30, 35]);
cellS = {S};
149 chars
8 lines

Note that automatic conversion only works for arrays with a single row or column. For arrays with multiple rows and columns, you'll need to use cell functions like num2cell or mat2cell to convert them to cell arrays.
