Hi, This seems pretty trivial, but I'm stuck on how to perform conditional application of a verb on a multidimensional array as defined by a bitmask of the same shape as the operand array. Is there a typical idiom for that?
For example, operand =. 2 2 2 $ 3 2 2 3 2 3 3 2 bitmask =. 2 2 2 $ 1 0 0 1 0 1 1 0 operator =. >: desired_result =. 2 2 2 $ 4 2 2 4 2 4 4 2 I tried looking at the doc, but I wasn't able to formulate a nice solution.
