ParametricOpInfOperator

class ParametricOpInfOperator

Template for operators that depend on external parameters, and which can be calibrated through operator inference, i.e., \(\Ophat_\ell(\qhat,\u;\bfmu) = \Ohat_\ell(\bfmu)\d_\ell(\qhat,\u)\).

Properties:

entries

Arrays that define the operator matrix as a function of the parameter vector.

parameter_dimension

Dimension \(p\) of the parameter vector \(\bfmu\) that the operator matrix depends on.

shape

Shape of the operator matrix when evaluated at a parameter value.

state_dimension

Dimension \(r\) of the state \(\qhat\) that the operator acts on.

Methods:

apply	Apply the operator to the given state and input at the specified parameter value, \(\Ophat_\ell(\qhat,\u;\bfmu)\).
copy	Return a copy of the operator.
datablock	Return the data matrix block corresponding to the operator.
evaluate	Evaluate the operator at the given parameter value, resulting in a nonparametric operator.
galerkin	Get the (Petrov-)Galerkin projection of this operator.
jacobian	Construct the state Jacobian of the operator, \(\ddqhat\Ophat_\ell(\qhat,\u;\bfmu)\).
load	Load an operator from an HDF5 file.
operator_dimension	Number of columns in the total operator matrix.
save	Save the operator to an HDF5 file.
set_entries	Set the arrays that define the operator matrix as a function of the parameter vector.
verify	Verify dimension attributes and evaluate().
