put "1,1:1;1,2:2;1,3:3" into x
split x using ";" and ":"
put "1,1:2;2,1:3;3,1:4" into y
split y using ";" and ":"
put matrixMultiply(x,y) into z
combine z using ";" and ":"
In hindsight, I think this might be more readable using space instead

Use combine as Jeanne explained and used above.

Yes and no.
You can make an array builder function that instantiates such an array
for the angle provided at build. Like this (off the top of my head):
function angleArray alpha
put atan(alpha) into a[1,1]
put cos(alpha) into a[1,2]
put sin(alpha) into a[1,3]
However, you might want to look at value(). You can evaluate a string
and strings can be array elements. Thus, you can have an array of
expressions. You can be as creative in expression processing as you
