Combine 2 Matrices

If you have a 3 plane matrix and a 4 plane matrix, and would like to combine these to create a 7 plane matrix, you would first unpack a multiple matrix into multiple single matrices using the jit.unpack object, and then combine again with the jit.pack object.

Copying one matrix to another

To set matrix “B” to have the contents of matrix “A”, you simply send “A” to “B”. (More specifically, you cause matrix “A” to send a jit_matrix message to matrix “B”.) The trick, though, is to suppress thruput on matrix “B” by setting its @thru attribute to 0 (it’s 1 by default), so that you can set and recall its contents independently.
