Matrix transposition: Difference between revisions

The GroovyCollections class provides a transpose method which will do the work for us:

<lang groovy>def matrix = [ [ 1, 2, 3, 4 ],

[ 5, 6, 7, 8 ] ]

matrix.each { println it}

println()

def transpose = GroovyCollections.transpose(matrix)

transpose.each { println it }</lang>

Output:

<pre>[1, 2, 3, 4]

[5, 6, 7, 8]

[1, 5]

[2, 6]

[3, 7]

[4, 8]</pre>
