Actually, I intended the integers in m to be indices into the right arg r. So if i scramble the indicies in m to create m1:
]m1=.0 1 5 3;4 2 8;7 6;9 ┌───────┬─────┬───┬─┐ │0 1 5 3│4 2 8│7 6│9│ └───────┴─────┴───┴─┘ Then the integers in each row of r should be scrambled according to the indices in m1.
