If you have graphics in /usr/bin, type "graphics"
and when you get the prompt "^" type
"whatis" - surprise! user-friendly help messages from
UNIX that tell you what you need to know.
Other useful math utilities are available to users include:
mean and variance, powers, roots, exponentials, logs, rand, etc.
These commands are in UNIX 1100 and an ATT SysV UNIX I checked.
They are in /usr/bin/graf and they understand vectors.
A table usually has to be "cut" and piped to produce the vectors appropriate
for the intended calculation.
Like a spreadsheet with a stick shift.
Have fun.
