Secondly, is it possible to plot the data? For example, if I have stored two column matrices in extended memory is it possible to plot one against the other (similar to a residual versus predicted plot in regression analysis) using prplot or the plot programs on the ppc module?

The SandMatrix Module manual has some additional information on the matrix file structure. It includes all the matrix functions from the Advantage plus many more on that subject. It also includes a "quick entry" mode using complete rows as inputs, as opposed to by single elements.

Look for "Sandmatrix" at TOS to download your copy.

I have a program to print matrices on the Thinkjet or 82905B - I can share it if anyone cares.
