.sfcr_broyden(m, equations, periods, max_ite, tol)The initialized matrix obtained with .make_matrix().
Prepared equations with .prep_equations().
Total number of rows (periods) in the model.
Maximum number of iterations allowed per block per period.
Tolerance accepted to determine convergence.
This function implements the Broyden method to solve the cyclical blocks of equations.
