WebThe gradient of a scalar function (or field) is a vector-valued function directed toward the direction of fastest increase of the function and with a magnitude equal to the fastest increase in that direction. It is denoted with the ∇ symbol (called nabla, for a Phoenician harp in greek).The gradient is therefore a directional derivative..
