Operate

Usage

• Operate[p, f[x, y]] gives p[f][x, y].
• Operate[p, expr, n] applies p at level n in the head of expr.

Notes

• Examples: Operate[p, f[x,y]]

; Operate[p, f[x][y][z], 1]

; Operate[p, f[x][y][z], 2]

• Operate[p, f[x]] effectively applies the functional operator p to the function f.

• Operate is essentially a generalization of Apply, which allows you to apply an operator to the head of an expression, rather than simply to replace the head.
