Eigenvalues

(This program is just a particular case of the more genereal program "Trajectories of eigenvalues".)(the comments in the program are in italian, i'm sorry)The program take as input the matrix A and an integer T. T define the accuracy of the plot. The program decompose A as A=D+E where D is the...

Program calculates eigenvalues, modal parameters and normalization constants for a thin circular plate with elastic edge supports. Both translational and rotational constraints are considered. User can modify the constraints and vary Poisson ratio.

Calculates the eigenvalues, state transition matrix, state vector and output of a linear system described in state space form.The answer is given in symbolic form.>> statespaceThe inputs A,B,C, and D must be given in matrix form.The input function or vector must be given in simple quotes.Ex:...
