% COMPDIR Computes a search direction in a subspace defined by Z.
% Helper function for NLCONST.
% Returns Newton direction if possible.
% Returns random direction if gradient is small.
% Otherwise, returns steepest descent direction.
% If the steepest descent direction is small it computes ...
%DEFINEV Scaling vector and derivative
%
% [v,dv]= DEFINEV(g,x,l,u) returns v, distances to the
% bounds corresponding to the sign of the gradient g, where
% l is the vector of lower bounds, u is the vector of upper
% bounds. Vector dv is 0-1 sign vector (See ?? for more detail.)

Tracking a moving object through several frames, provided changes from frame to frame are on the order of +-(10 + "X Range") pixels in the X direction and +-(10 + "Y Range") in the Y direction is done automatically because of a relatively large area of exploration during the search for an optimal (n ...

Hybrid Monte Carlo sampling.SAMPLES = HMC(F, X, OPTIONS, GRADF) uses a hybrid Monte Carlo
algorithm to sample from the distribution P ~ EXP(-F), where F is the
first argument to HMC. The Markov chain starts at the point X, and
the function GRADF is the gradient of the `energy function F.
sfrmat is a Matlab function that provides a spatial frequency response* (SFR) from a digital image file containing a slanted-edge feature. The specific edge-gradient algorithm follows the intent of the standard ISO 12233, developed by Technical Committee ISI/TC 42, for resolution measurements for el ...
用于汽车巡航控制系统的模糊控制算法,以及如何利用梯度下降法和卡尔曼滤波来优化模糊控制器的算法。The files illustrate a simple fuzzy control algorithm as applied to an automobile cruise control system. The files also illustrate how gradient descent and Kalman filtering can be used to optimize the fuzzy ...
