<span
class="phvr7t-x-x-80">nip2 </span>has four ways of displaying a matrix, but they all
behave in the same way under the skin. Almost all the items
in the <span
class="phvr7t-x-x-80">Math </span>menu will work on matricies. Most of the matrix
operations will also work on images.

class="description">The first four items make matricies which display
and edit in various ways useful for different
applications. The final two make matricies which
are pre-filled with useful numbers.

extracts various submatricies. You can also do this
graphically: just drag-select an area in matrix.
