Information
Vibrating string equation
Implements the vibrating string equation. The finite vibrating string of length L (L = 1 in this problem) is described by the wave equation together with special boundary and initial conditions. The complete problem is
where c is a constant value.
The analytical solution of this problem is implemented in VibratingStringAnalytical block.
