I have a NxN matrix.
For each 2x2 subarray of this (keep it simple, N is even), I want to calculate
the maximum value and if the value of that cell equals the maximum of the 2x2
subarray write 1, else write 0.
e.g.
NB. T arbitrary 10x10 matrix
T =: 10 10 $ 0 _2 12 100 2 4.5 1 7 _5.5 3.2 120 2 _
13 matches
