% @brief MATLAB Coder script to generate MEX functions for cache_ module.
%
% This script generates MEX (MATLAB Executable) versions of cache_ functions
% for improved performance. Cache functions compute hit/miss probabilities
% and normalizing constants for cache replacement models.
%
% Skipped functions (Coder-incompatible):
%   cache_mva        - State.cartesian() OOP dependency
%   cache_t_hlru     - nested bisection helper (function handles)
%   cache_ttl_lrua   - fsolve() + rng() + function handles
%   cache_rrm_meanfield - ode23s() script (not a function)
