A multistage pseudospectral collocation method based on Chebyshev polynomial expansion for solving first-order ODEs. The approach splits theproblem into two independent subproblems: finding solutions satisfying the differential equation, then applying initial/boundary conditions. Results show 1.5–3 orders of magnitude better accuracy than comparable methods.
