Gradient (disambiguation)

Look up gradient in Wiktionary, the free dictionary.

Gradient in vector calculus is a vector field representing the maximum rate of increase of a scalar field or a multivariate function and the direction of this maximal rate.

Gradient may also refer to:

• Gradient sro, a Czech aircraft manufacturer
• Image gradient, a gradual change or blending of color
  • Color gradient, a range of position-dependent colors, usually used to fill a region
  • Texture gradient, the distortion in size which closer objects have compared to objects farther away
• Spatial gradient, a gradient whose components are spatial derivatives
• Grade (slope), the inclination of a road or other geographic feature

Mathematics

• Gradient descent, a first-order iterative optimization algorithm for finding the minimum of a function
• Gradient theorem, theorem that a line integral through a gradient field can be evaluated by evaluating the original scalar field at the endpoints of the curve
• Gradient method, an algorithm to solve problems with search directions defined by the gradient of the function at the current point
• Conjugate gradient method, an algorithm for the numerical solution of particular systems of linear equations
• Nonlinear conjugate gradient method, generalizes the conjugate gradient method to nonlinear optimization
