df = fndir(f,y)is the ppform of the directional derivative, of the functionfinf, in the direction of the (column-)vectory. This means thatdfdescribes the functionDyf(x):=limt→0(f(x+ty)−f(x))/t. Ifyis a matrix, withncolumns, andfisd-valued, then the function indfisprod(d)...

For a function u(x,y) that describes a surface in 3-D space, the surface area can be determined by the functional F[u]=∫y2y1∫x2x1f[x,y(x),u(x,y),ux,uy]dxdy=∫y2y1∫x2x1√1+u2x+u2ydxdy where ux and uy are the partial derivatives of u with respect to x and y. Fi...
The paper deals with six approaches how to determine a derivative of the matrix exponential function in the Matlab language environment. Namely, a Taylor series expansion, an augmented matrix utilization, an eigenvalues decomposition, a Laplace transform approach, a convolution integral evaluation and a...
This MATLAB function compares the value of the supplied first derivative function in fun at a point near x0 against a finite-difference approximation.
(i.e. thetad - velocity, and thetadd - acceleration). These variables have all been defined symbolically. I am attempting to take the time-derivative of a function using these variables, but have been getting 0 as a result. Below is the code, the 'diff' call yielding 0...
