### Gradient

A slope or incline. In plant pathology, an observed progressive change with distance of the concentration of spores, lesions or diseased plants, or in the value of an environmental attribute.

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

(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 ...

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.
