- iboss_od.m: Native MATLAB port of the R iboss.od() function for Information-Based Optimal Subdata Selection in linear regression. Supports both univariate and multivariate covariates, with optional intercept adjustment using full-data means. - iboss_demo.m: Demo script replicating the R package example with multivariate t-distributed covariates, including comparison against full-data OLS. https://claude.ai/code/session_01LaRwUj5TgHCq2hKP3puUJR
…DxKuL Add MATLAB implementation of IBOSS algorithm
Translates the MATLAB experimental script to R, using the original iboss.od() function with its compiled C++ backend (getIdx/getIdxR) instead of the pure-MATLAB reimplementation. Reads .mat data files via R.matlab::readMat and computes the D-optimality objective log(det(X_S * X_S')) for each problem instance. https://claude.ai/code/session_01TYn581iJVFKwrT3BYBJvBP

…anslation Port getIdx() and getIdxR() from src/getIdx.cpp (R C API) to MATLAB MEX API, preserving the same O(n) std::nth_element algorithm. iboss_od_mex.m mirrors iboss.r by delegating index selection to the compiled C++ routines. New files: - matlab/getIdx_mex.cpp – MEX port of getIdx (unrestricted) - matlab/getIdxR_mex.cpp – MEX port of getIdxR (restricted, with exclusion) - matlab/iboss_od_mex.m – iboss_od rewritten to call MEX functions - matlab/compile_mex.m – one-step build script https://claude.ai/code/session_01TYn581iJVFKwrT3BYBJvBP
