The matrix library uses arrays to represent the matrices.
An 2x3 matrix can be constructed as:
(matrix/dim 2 3
1 2 3
4 5 6)
(list->matrix '[[1 2 3] [4 5 6]])
(for/matrix: : Number 2 3 ([i (in-naturals)]) i)
These expressions will all return the same 2D array.
Given that the shape of a matrix is fixed, the problems
with square parentheses in constructor notation disappear.
That is, one could let matrix be a macro, and it could
accept both kinds of parentheses:
(matrix [[1 2 3] [4 5 6]])
(matrix ((1 2 3) (4 5 6)))
I wouldn't mind having a special constructor like that for matrices.
BTW, I've just pushed the documentation for `math/statistics' v1.0, so
it's ready for testing. That also means I'll be reviewing `math/matrix'
soon. Woo hoo!
