<title>Description</title>
<para><literal>and(A)</literal> is the logical AND of elements of the
boolean matrix <literal>A</literal>. <literal>and(A)</literal> returns
<literal>%T</literal> ("true") iff all entries of <literal>A</literal> are
<literal>%T</literal>.</para>
<para><literal>y=and(A,'r')</literal> (or, equivalently,
<literal>y=and(A,1)</literal>) is the rowwise and. It returns in each
entry of the row vector <literal>y</literal> the and of the rows of
<literal>x</literal> (The and is performed on the row index :
<literal>y(j)= and(A(i,j),i=1,m)</literal>).</para>
<para><literal>y=and(A,'c')</literal> (or, equivalently,
<literal>y=and(A,2)</literal>) is the columnwise and. It returns in each
entry of the column vector <literal>y</literal> the and of the columns of
<literal>x</literal> (The and is performed on the column index:
<literal>y(i)= and(A(i,j),j=1,n)</literal>)).</para>
