In this exercise we will learn how to create a basic finite element gradient matrix. The gradient vector field is tangent to the surface and is the linearization of the function there. On flat ...

Edge-Detection-using-directional-gradients This is a MATLAB demo to elaborate the idea of boundary tracing objects in image using directional gradients In any image the edges lie where the rate of ...

We now present a simple and general numerical implementation of 3D cross-gradients joint inversion frame- work for gravity and magnetic data in the MATLAB programming environment, noted for its ...

This paper describes a new algorithm with neuron-by-neuron computation methods for the gradient vector and the Jacobian matrix. The algorithm can handle networks with arbitrarily connected neurons.

Nonnegative matrix factorization (NMF) can be formulated as a minimization problem with bound constraints. Although bound-constrained optimization has been studied extensively in both theory and ...
