MATLAB Programming

2 Data Types
3–by-3 Cell Array
Note If you already have a numeric array of a given name, don’t try to
create a cell array of the same name by assignment without first clearing
the numeric array. If you do not clear the numeric array, MATLAB assumes
that you are trying to “mix” cell and numeric syntaxes, and generates an
error. Similarly, MATLAB does not clear a cell array when you make a single
assignment to it. If any of the examples in this section give unexpected
results, clear the cell array from the workspace and try again.
Alternative Assignment Syntax. When assigning values to a cell array,
either of the syntaxes shown below is valid. You can use the braces on the
right side of the equation, enclosing the value being assigned as shown here:
A(1,1) = {[1 4 3; 0 5 8; 7 2 9]};
A(1,2) = {'Anne Smith'};
Or use them on the left side, enclosing the array subscripts:
A{1,1} = [1 4 3; 0 5 8; 7 2 9];
A{1,2} = 'Anne Smith';
