Each (with Monadic Operand) {R}←f¨Y

f may be any monadic function. Y may be any array, each of whose items are separately appropriate to function f.

The derived function applies function f separately to each item of Y. The derived function need not return a result. If a result is returned, R has the same shape as Y, and its elements are the items produced by the application of function f to the corresponding items of Y.

If Y is empty, the prototype of R is determined by applying the operand function once to the prototype of Y.
