get_structural_incidence_matrix

(function from pyomo.contrib.incidence_analysis.interface)

pyomo.contrib.incidence_analysis.interface.get_structural_incidence_matrix(variables, constraints, **kwds)[source]

Return the incidence matrix of Pyomo constraints and variables

Parameters:

  • variables (List of Pyomo VarData objects)

  • constraints (List of Pyomo ConstraintData objects)

  • include_fixed (Bool) – Flag for whether fixed variables should be included in the matrix nonzeros

Returns:

COO matrix. Rows are indices into the user-provided list of constraints, columns are indices into the user-provided list of variables. Entries are 1.0.

Return type:

scipy.sparse.coo_matrix
