Display an array as a matrix in a new figure window.

The origin is set at the upper left hand corner and rows (first
dimension of the array) are displayed horizontally. The aspect
ratio of the figure window is that of the array, unless this would
make an excessively short or narrow figure.
The origin is set at the upper left hand corner.
The first dimension of the array represents the length of the vertical column
the second dimension of the array represents the length of the
horizontal column. The aspect ratio of the figure window is that of the array,
unless this would make an excessively short or narrow figure.

Tick labels for the xaxis are placed on top.
