Define the length, density, and tension as constants for later use. The string has a characteristic density per unit length and a characteristic tension.

You can apply the techniques illustrate in this example to applications in the calculus of variations from solving the Brachistochrone problem to finding minimal surfaces of soap bubbles.Д¬onsider a string of length L suspended between the two points x = 0 and x = L. It describes the motion of waves, from the motion of a string to the propagation of an electromagnetic wave, and is an important equation in physics. Solving the wave equation is one application of functional derivatives. The WFDB Toolbox for MATLAB v.6.0.290.11. If you want to add a new assumption to the existing assumptions, use assumeAlso. For example, assume that the variable x is nonnegative: syms x assume (x > 0) assume replaces all previous assumptions on the variable with the new assumption. MATLAB R2008a 7.6 is a language for technical computing that integrates computation, visualization. To set an assumption on a symbolic variable, use the assume function. The Symbolic Math Toolboxв„ў implements functional derivatives using the functionalDerivative function. Symbolic Math Toolbox Matlab Download Symbolic Math Toolbox For Matlab 2008a New notebook interface in Symbolic Math Toolbox for managing and documenting symbolic. A functional derivative is the derivative of a functional with respect to the function that the functional depends on. The wave equation for a string fixed at its ends is solved using functional derivatives. This example performs calculations symbolically to obtain analytic results.
