Lisp not needed for this:
m1: matrix([2,3],[4,5]);
m2: matrix([6,7],[8,9]));
map(append,m1,m2);
This takes advantage of the representation of matrices as lists of rows.
To concatenate "vertically", use transpose:
transpose(map(append,transpose(m1),transpose(m2)));
> It would also be great if matrix( a,b,c,.. ) could work with matrix columns as well as with rows.
Simple solution:
transpose(matrix(...))
