Summary
This PR introduces a new C API interface (
interface.c/interface.h) that allows users to directly construct and solve LPs from in-memory data structures, without requiring MPS files.Key Changes
interface.candinterface.h:make_problem_from_matrix(...)for constructing LP problems from dense/CSR/CSC/COO matrices.solve_lp_problem(...)for solving the constructed problems with optional custom PDHG parameters.README.md:test/that demonstrates solving a toy LP using the interface.
