This script may be easily converted to a function which could be an extremely useful subroutine in optimization problems to check whether the objective function is globally convex. It may also be used to derive the expressions for gradient and Hessian of the given multidimensional real valued... Platforms: Matlab

The large classification margin is the most usual approach to achieve good generalization. The most known maximal margin algorithm is SVM, for which different kernels have been investigated. Unfortunately, in the context of some real world problems, such as on-the-fly object detection, the use of... Platforms: Matlab

Simulation of Absolute-Value Output Circuit is carried out with operational amplifier,diodes and other components available in Simscape 2.1 version. Regardless of the polarity of the input signal, the output of the circuit is always positive going and this is displayed in the scopes. Platforms: Matlab
