datablock()#

classmethod InterpQuadraticOperator.datablock(parameters, states, inputs=None) → ndarray#

Return the data matrix block corresponding to the operator.

For interpolated operators, this is a block diagonal matrix where the $i$-th block is the data block for the corresponding nonparametric operator class with the state snapshots and inputs for training parameter ${\mathit{\mu }}_i$.

Parameters:

parameters(s, p) ndarray

Traning parameter values ${\mathit{\mu }}_0,\dots ,{\mathit{\mu }}_{s-1}$.

stateslist of s (r, k) or (k,) ndarrays

State snapshots for each of the s training parameter values. If each snapshot matrix is 1D, it is assumed that $r=1$.

inputslist of s (m, k) or (k,) ndarrays

Inputs corresponding to the state snapshots. If each input matrix is 1D, it is assumed that $m=1$.

Returns:

block(sd, sk) ndarray

Data block for the interpolated operator. Here, d is the number of rows in the data block corresponding to a single training parameter value.
