<para><literal>cell(x) </literal>is not the same size that

<para><literal>cell()</literal> is equivalent to
<literal>cell(0)</literal>.</para>
<para>If A is a cell array, you can access the contents of an element of A
by using <literal>A(m1, m2, ..., mn).entries</literal>, the expression
<literal>A(1,1) = zeros(2,2)</literal> is not valid, the right syntax is
<literal>A(1,1).entries = zeros(2,2)</literal>.</para>
<para>If A is a cell array, you can get its dimensions by using
<literal>A.dims</literal>.</para>
