The slope of a non-linear function is different at different points along the function. The slope may be positive, negative or zero as indicated by the tangent lines in the following chart.

This repository hosts Python projects that implement Gradient Descent from scratch for optimizing both 2D and 3D functions. The projects aim to provide a comprehensive understanding of the gradient ...

Vary the aspect ratio of the surface. Vary colour map and mode according to height or slope. The possibility to choose between the four smoothstep functions by modifying the interpolation and thus ...

Non-linear optimal control problems often require solution using iterative procedures and, hence, they fall naturally in the realm of 2D systems where the two dimensions are response time horizon and ...

Learn how to use the gradient tool and the gradient map adjustment layer in Photoshop to create color effects for your 2D graphics. Discover different types of gradients and how to customize them.

In this paper we describe a new variational approach for the detection of fine structures in an image (like filaments in 2D). This approach is based on the computation of the topological gradient ...
