Fast linear algebra is stable
WebWe propose a fast algorithm for computing optimal viscosities of dampers of a linear vibrational system. We are using a standard approach where the vibrational system is first modeled using the second-order structure. This structure yields a quadratic eigenvalue problem which is then linearized. Optimal viscosities are those for which the trace of the … WebLinear algebra is the branch of mathematics concerning linear equations such as: + + =, linear maps such as: (, …,) + +,and their representations in vector spaces and through …

WebSolving linear systems of equations is straightforward using the scipy command linalg.solve. This command expects an input matrix and a right-hand side vector. The solution vector is then computed. An option for entering a symmetric matrix is offered, which can speed up the processing when applicable.
