What is the meaning of Gradient?

A slope or incline.

A rate of inclination or declination of a slope.

The ratio of the rates of change of a dependent variable and an independent variable, the slope of a curve's tangent.

The rate at which a physical quantity increases or decreases relative to change in a given variable, especially distance.

A differential operator that maps each point of a scalar field to a vector pointed in the direction of the greatest rate of change of the scalar. Notation for a scalar field φ: φ

A gradual change in color; a color gradient; gradation.

Moving by steps; walking.

Rising or descending by regular degrees of inclination.

Adapted for walking, as the feet of certain birds.
