The integrator class now includes support for a piecewise constant control ( u).Unlike before, this support should now work in combination with forward/adjoint sensitivity analysis (to any order) and sparsity pattern calculations. It can now be obtained by providing a time grid to the integrator constructor. The integrator class now has a much more mature support for returning the IVP solution at multiple time points.The Integrator class, which solves initial-value problems in ODEs and DAEs has been thoroughly refactored. SqpMethod Eigen-reflect/eigen-clip incorrect #2896.CPLEX interface will dynamically load libcplex, where CPLEX_VERSION is read from environmental variables.nlpsol/ Opti.solver can now take an option ‘detect_simple_bounds’ (default False) that will promote general constraints to simple bounds (lbx/ubx).Function objects with an external call can now be codegenerated.The f output is not used internally, so will be logged as nan. Ipopt nlp_grad_f has two outputs, f and grad_f_x. breaking: Function outputs that are not used (passed a null pointer internally) will be logged ( dump_in option ) as nan instead of earlier 0.Function.find_function Can be used to retrieve Functions in a hierarchy.breaking Changed API part for Jacobian sparsity (relevant for advanced use through external or Callback)īool has_jac_sparsity ( casadi_int oind, casadi_int iind ) const override Sparsity get_jac_sparsity ( casadi_int oind, casadi_int iind, bool symmetric ) const override.The Function must now return individual blocks (Jacobian of an output w.r.t. breaking custom_jacobian semantics changed.breaking Serialization: files saved with CasADi 3.5.5 will load in CasADi 3.6.0 (unittested), except for Functions that include a ‘mumps’ linear solver since serialization of this solver was deficient, and except for Functions that include an Integrator.breaking SX/ MX Function construction now fails if there are duplicates in input names or output names, unless the allow_duplicate_io_names option is used #2604.symbols used in the output expressions that are not declared as inputs) now fails immediately unless the allow_free option is used. breaking SX/ MX Function construction with free variables (i.e.There is a function cse() that you may apply to expressions:Ĭasadi :: MX A = casadi :: MX :: sym ( "A", casadi :: Sparsity :: upper ( 2 )) casadi :: MX b = casadi :: MX :: sym ( "b", 2 ) casadi :: MX x = solve ( A, b ) // for argument-dependent lookup, alternatively casadi::MX::solve(A, b) for static function Added Common Subexpression Elimination #1540 for MX and SX.ĬasADi can now efficiently eliminate redundant computation by inspecting an expression graph and removing redundant nodes.īefore, CasADi internals would avoid introducing redundant nodes during operations on a given expression, but the user was responsible to avoid duplication when constructing that expression. ![]() DAE index reduction support (Pantelides structural algorithm) See.numpy.mod has no counterpart in CasADi only fmod is equivalent. CasADi-Python mod has been removed, because its numerical behaviour is not like numpy.mod. The builtin-Matlab mod has no CasADi counterpart. breaking CasADi-Matlab mod has been renamed to rem, because its numerical behaviour is like the builtin-Matlab rem.breaking vertcat/ vcat, horzcat/ hcat, etc now return a DM type instead of a Sparsity type #2549.Added logsumexp which behaves like log(sum(exp(x))) but is numerically more accurate (and no overflow issues).Jacobian(fmin(x,y),vertcat(x,y)) used to be for x=y. breaking AD rule of fmin/fmax` is now symmetric:.Added operation remainder with the semantics of the C operation. ![]()
