MVAX5D plots a 4 or 5-d surface by plotting slices through the 3rd and 4th dimensions in a 2-d array of of 3-d plots. Each 3-d surface plots d(*) as a function of 2 of the dimensions using MVAX3D.
Origin of the plot is in the lower-left corner. The X axis runs left to right along the subplot bottom. The Y axis is plotted out the page of the subplot (see MVAX3D). The Z axis runs left to right in subplots with the W axis vertical subplots.

----------> Z
Since the subplots may runoff the edge of the plotting page, the routine includes a page size option to issue a NEWPAGE and plot the additional subplots on separate pages. A shrinking factor is included to shrink the subplots. Labeling of the W and Z axis is due in the lower right hand corner. Each subplot is further tagged with the corresponding W and Z axis value. A multiple page plot can be pasted together to form a large representation of a 5-d (or 4-d) surface.
