• combine : Rather than listing the elements, the elements are combined using the function. Since: 3.0

Examples

use <util/zip.scad>;
use <util/sum.scad>;

xs = [10, 20, 30];
ys = [5, 15, 25];
zs = [2.5, 7.5, 12.4];

assert(zip([xs, ys, zs]) == [[10, 5, 2.5], [20, 15, 7.5], [30, 25, 12.4]]);

sum_up = function(elems) sum(elems);
assert(zip([xs, ys, zs], sum_up) == [17.5, 42.5, 67.4]);
