Function select_node

ciphercore-base/src/mpc/utils.rs:219–226

Selects elements of node 0 if bits of node b are zero and elements of node 1 otherwise. Broadcasting is applied # Arguments - `a0` - node 0 containing an array - `a1` - node 1 containing an array of the same type as `a` - `b` - node containing selection bits # Returns Node containing an array with selected elements of `a0` or `a1`

(b: Node, a1: Node, a0: Node)
