Hi @akosua00

Apologies for the delay in review. Since the person originally assigned to your PR has left the team, I'll now be reviewing the PR instead. As a first step, could you kindly resolve all the merge conflicts in the PR? Thanks! 🙂

Hi @akosua00
Thanks for the PR
This functional implementation would require an accompanying test. Could you please add the test similar to other experimental functions under ivy_tests/test_ivy/test_functional/test_experimental
Please request a review when done. Thanks :)
