<title>Descrio</title>
<para>O tipo hipermatriz ("hypermatrix") permite manipular arrays
multidimensionais.</para>
<para>Hipermatrizes podem ser definidas por uma extenso das matrizes 2D
como segue: a=[1 2;3 4];a(:,:,2)=rand(2,2)</para>
<para>ou usando a funo <literal>hypermat</literal> diretamente.</para>
<para>As entradas podem ser nmeros reais ou complexos, polinmios, razes
de polinmios, strings ou valores booleanos.</para>
<para>Hipermatrizes so <literal>mlists</literal>:
<literal>mlist(['hm','dims','entries'],sz,v)</literal> onde
<literal>sz</literal> o vetor linha de dimenses e <literal>v</literal>
o vetor coluna de entradas (as primeiras dimenses so armazenadas
primeiro)</para>
<para>NOTAS: O nmero de dimenses de hipermatrizes com tamanhos mais
direita iguais a 1 automaticamente reduzido. Uma hipermatriz com apenas
duas dimenses automaticamente trocada por uma matriz regular (tipo
1).</para>
