Element-wise operations: Difference between revisions

=={{header|Sidef}}==

The built-in metaoperators `~W<op>`, `~S<op>` and `~RS<op>` are defined for arbitrary nested arrays.

<lang ruby>var m1 = [[3,1,4],[1,5,9]]

var m2 = [[2,7,1],[8,2,2]]

say (m1 ~W+ m2)

say (m1 ~W- m2)

say (m1 ~W** m2)

say (m1 ~W% m2)
