Special identity matrix with two diagonals
Wren
A terminal based solution as I don't like asking people to view external images. <lang ecmascript>var specialMatrix = Fn.new { |n|
for (i in 0...n) { for (j in 0...n) { System.write((i == j || i + j == n - 1) ? "1 " : "0 ") } System.print() }
}
specialMatrix.call(6) // even n System.print() specialMatrix.call(7) // odd n</lang>
- Output:
1 0 0 0 0 1 0 1 0 0 1 0 0 0 1 1 0 0 0 0 1 1 0 0 0 1 0 0 1 0 1 0 0 0 0 1 1 0 0 0 0 0 1 0 1 0 0 0 1 0 0 0 1 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 1 0 0 0 1 0 0 0 1 0 1 0 0 0 0 0 1
