4 Programming

This is because the first two cells are too large to print in this limited space,

but the third cell contains only a single number, 16!, so there is room to print it.

Here are two impo rtant points to remember. First, to retrieve the contents of

one of the cells, use subscripts in curly braces. For example,

C{1} retrieves

the magic square and

C{3} is 16!. Second, cell arrays contain copies of other

arrays, not pointers to thos e arrays. If you subsequently change

A, nothing

happens to

You can use three-dimensional arrays to store a sequence of matrices o f the

same size. C ell arrays can be used to store a sequence of matrices of different

sizes. For example,

M = cell(8,1);

for n = 1:8

M{n} = magic(n);

end

produces a sequence of magic squares of different order:

[1]

[ 2x2 double]

[ 3x3 double]

[ 4x4 double]

[ 5x5 double]

[ 6x6 double]

[ 7x7 double]

[ 8x8 double]
