I have a legacy C MEX source file (`spectral_smooth.c`) that uses traditional complex array pointers like `mxGetPr` and `mxGetPi`. I want to modernize this file to support modern MATLAB interleaved complex memory layout. Please audit the source code to report the count of outdated API calls and their performance implications on complex data, ask me about output file targets and backward-compatibility build options before generating code, provide the refactored C source code, give compilation commands, and supply a MATLAB test script to verify numerical equality against the original build.

Convert C, C++, and Fortran MEX source files from the Separate Complex (SC) API to the Interleaved Complex (IC) API, following the MathWorks upgrade workflow with guardrails for SC/IC guarded builds using MX_HAS_INTERLEAVED_COMPLEX, required vs recommended changes, and verification.
