1. 
   Gradient
   A vector of partial derivatives of a function that operates on vectors. Intuitively, the gradient represents the slope of a high-dimensional surface.

2. 
   Gradient
   (1) A measure of slope (soil- or water-surface) in meters of rise or fall per meter of horizontal distance. (2) More general, a change of a value per unit of distance, e.g. the GRADIENT in longshore transport causes EROSION or ACCRETION. (3) With reference to winds or currents, the rate of increase or decrease in speed, usually in the vertical; or the curve that represents this rate.

   Gradient
   Also called slope. The gradient indicates how steeply a line slopes. You will come across this when using the linefitting technique. A line is described by its gradient and intercept, the point at which the line crosses the y-axis. See also Linefitting.

    Definition (keystage 3) The slope of a line, at a particular point. A horizontal line has gradient 0; a vertical line has infinite (undefined) gradient. <br /> The gradient of a straight line is equal to the change in y coordinate divided by the corresponding change in x coordinate. <br /> Gradient is the tangent of the angle between th ...

    Gradient
    In vector calculus, the `gradient` of a scalar field is a vector field which points in the direction of the greatest rate of increase of the scalar field, and whose magnitude is the greatest rate of change. A generalization of the gradient, for functions on a Banach space which have vectorial values, is the Jacobian.
