Matrix

Z←f⌻R			applies the monadic function f to the (square) diagonalizable matrix R as a whole and returns the resulting matrix. The shape of the result is ⍴R.
Z←Lf⌻R			applies the monadic derived function L∘f to the (square) diagonalizable matrix R as a whole and returns the resulting matrix. L is a scalar. The shape of the result is ⍴R.
Z←∘⌻R			for scalar R, returns a (square) matrix representation of the Hypercomplex number R. The shape of the result is 2⍴=R.
Z←∘⌻R			for vector R, returns a (square) diagonal matrix with the items in R inserted into the diagonal. R may be a simple or nested vector. In the latter case, the items of R must be simple numeric scalars, vectors, or matrices. The shape of the result is 2⍴+/≢¨R.
