The scalable discipline.

class ScalableDiscipline(index, a_i, D_i0, D_ii, C_ij, **default_input_values)[source]#

A scalable discipline.

It computes the output \(y_i=a_i-D_{i,0}x_0-D_{i,i}x_i+\sum_{j=1\atop j\neq i}^N C_{i,j}y_j\).

Initialize self. See help(type(self)) for accurate signature.

Parameters:

index (int) -- The index \(i\) of the scalable discipline.
a_i (NDArray) -- The offset vector \(a_i\).
D_i0 (NDArray) -- The coefficient matrix \(D_{i,0}\) to multiply the shared design variable \(x_0\).
D_ii (NDArray) -- The coefficient matrix \(D_{i,i}\) to multiply the local design variable \(x_i\).
C_ij (Mapping[str, RealArray]) -- The coefficient matrices \(\left(C_{i,j}\right)_{j=1\atop j\neq i}^N\) where \(C_{i,j}\) is used to multiply the coupling variable \(y_j\).
**default_input_values (RealArray) -- The default values of the input variables.
