Solves the polynomial eigenvalue problem.
Array of size n × n × p that contains square input matrices of the same size. The matrices are in ascending order of power for eigenvalues.
This input accepts a 3D array of double-precision, floating-point numbers or a 3D array of complex double-precision, floating-point numbers.
A value specifying whether this node computes eigenvalues and vectors.
Name | Value | Description |
---|---|---|
Eigenvalues | 0 |
The node computes only the eigenvalues of the input matrix. |
Eigenvalues and Vectors | 1 |
The node computes both the eigenvalues and the eigenvectors of the input matrix. |
Default: Eigenvalues and Vectors
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Vector of n * p elements that contains the computed eigenvalues.
Matrix of size n × (n * p) that contains the computed eigenvectors in its columns.
Error information.
The node produces this output according to standard error behavior.
