has_a
Whether a second-order expert result contains an accepted a profile.
copp.solver.copp2_socp.Result
COPP2-SOCP expert result with Clarabel diagnostics.
Description
Result is returned by solve_expert(). The accepted a(s) profile is stored in A only when HAS_A is true. A is an s_len-by-1 double column vector. Raw Clarabel vectors X, Z, and S are also stored as double column vectors. Diagnostics are populated regardless of whether the final solver status is accepted.
Input Arguments
a
Second-order node profile. Element a(k) stores the squared path speed \((ds/dt)^2\) at station s(k).
x
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
z
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
s
Station grid or path-parameter samples. Use a real finite vector; station-grid inputs are usually strictly increasing.
solver_status
Backend solver status normalized to a lower-snake-case MATLAB string.
obj_val
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
obj_val_dual
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
solve_time
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
iterations
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
r_prim
Input value for copp.solver.copp2_socp.Result. See Description for accepted shape and constraints.
