operator_dimension()

AffineCubicOperator.operator_dimension(s: int, r: int, m: int) → int

Number of columns in the concatenated operator matrix.

For affine operators, this is \(A_{\ell}\cdot d(r,m)\), where \(A_{\ell}\) is the number of terms in the affine expansion and \(d(r,m)\) is the dimension of the function \(\d(\qhat,\u)\).

Parameters:

sint

Number of training parameter values.

rint

State dimension.

mint or None

Input dimension.

Returns:

dint

Number of columns in the concatenated operator matrix.
