Matrix transposition: Difference between revisions

Functional style (same output):

<lang>import std.stdio, std.algorithm, std.conv, std.range;

auto transpose(T)(in T[][] m) {

return map!((int i){ return transversal(m,i); })(iota(m[0].length));

}

void main() {

auto M = [[10, 11, 12, 13],

[14, 15, 16, 17],

[18, 19, 20, 21]];

auto Mt = transpose(M);

writeln("[", array(map!text(Mt)).join("\n "), "]");

}</lang>
