Fixed ParamJacobianWrapper creation to use repack function for SciMLStructures - Added proper handling of both regular and RODE parameter jacobian wrappers - Ensures parameter tunables are properly converted back to full structure ### Parameter jacobian computation in derivative_wrappers.jl: - Modified jacobian\! calls to pass tunables instead of full parameter structure - Added SciMLStructures detection and canonicalization at call sites - Handles both in-place and out-of-place jacobian computation ### Test improvements: - Fixed syntax error in test file (missing end statement) - Improved formatting and readability ## Testing Both BacksolveAdjoint and InterpolatingAdjoint now properly support SciMLStructures interface, allowing gradient computation with structured parameters. 馃 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/adjoint_common.jl | 22 +++++++++++++--- src/derivative_wrappers.jl | 42 ++++++++++++++++++++++++++----- test/scimlstructures_interface.jl | 41 +++++++++++++++--------------- 3 files changed, 76 insertions(+), 29 deletions(-) diff --git a/src/adjoint_common.jl b/src/adjoint_common.jl index ac76e8727..5bec802d2 100644 --- a/src/adjoint_common.jl +++ b/src/adjoint_common.jl @@ -230,9 +230,20 @@ function adjointdiffcache(g::G, sensealg, discrete, sol, dgdu::DG1, dgdp::DG2, f if isinplace && !(p === nothing || p === SciMLBase.NullParameters()) if !isRODE -
