error_solver.solvers.SolverPipeline

class error_solver.solvers.SolverPipeline(solvers, links, combos=None)

A class for performing propagation error analysis for multiple ErrorSolver or ErrorSolverPy solvers in series.

Parameters:

solvers : list

A list of ErrorSolver of ErrorSolverPy to be solved in sequence.

links : list

A list of dictionaries with error variables to be passed from one solver to the next.

combos : list

A list of equation combinations to use for each solver. If None, all equations will be applied.

Examples

# pipeline_ex1.py
from error_solver import get_file_path, ErrorSolver, SolverPipeline

solvers = [
    ErrorSolver.from_file(get_file_path('area.ef')),
    ErrorSolver.from_file(get_file_path('volume.ef')),
]

links = [
    {'area': 'area'}
]

values = [
    {'radius': 5, 'area': 78.539816},
    {'height': 12, 'area': 78.539816, 'volume': 942.477796},
]

errors = [
    {'radius': 0.05},
    {'height': 0.05},
]

pipe = SolverPipeline(solvers, links)
pipe.solve(values, errors)

Methods

solve(self, values, errors[, consts, check, …])

Solves for the propagation errors of the pipeline and returns a Data Frame of the results.
