I also know that it is a challenge to do what I am trying to do with computing the gradient using data points from two rows of cells above the surface and the cells just above the surface (since I have been trying for the past week or so), which is the reason why I post...

Similarly to the subgradient, it is a non-monotone method and the steplength along the gradient, instead of being provided by a line search, is calculated on the basis of a two-point approximation of the Hessian matrix, taken as a scalar multiple of the identity matrix. More specifically, ...
The objective function has two outputs, energy and gradenergy. Put both functions in one vector when calling matlabFunction to reduce the number of subexpressions that matlabFunction generates, and to return the gradient only when the calling function (fmincon in this case) requests both outputs. ...
You may have seen surveyors working on-site to find out the angle of the sun, the wind and the gradient in order to reach the best parameters for a building design and infrastructure. They employ several trigonometric calculations and ratios to find out the important measurements and then use...
