So, instead of a single column from an incoming, 2 dim, multiple planes matrix, I want 

, with one dimension of my new matrix being a column from the original matrix and the second dimension being a cut across all the planes of the original matrix.

Should I use jit.expr or is there a dedicated object for such tasks?

jit.unpack, jit.dimmap, jit.glue, jit.matrix (source and destination dim start and end).

Useful objects:
jit.unpack, jit.dimmap, jit.glue, jit.matrix (source and destination dim start and end).

Yes, I made it using jit.unpack and jit.glue but I can't find a way to achieve this with a single object.

There isn't one, AFAIK. I'd use jit.submatrix and sautée it lightly in some butter and a sprig of rosemary, myself.
