Cache Memory and Matrix Multiplication in MATLAB
=================================================

Contents
--------
matmul_ijk.m             Explicit i-j-k loop implementation
matmul_kji.m             Explicit k-j-i loop implementation
matmul_blocked.m         Blocked matrix multiplication implementation
cache_matrix_lab.m       Main experiment script
MATLAB_Student_Guide.md  Student instructions and analysis questions

How to run
----------
1. Put all .m files in the same folder.
2. Open MATLAB and set the current folder to that folder.
3. Run: cache_matrix_lab

The script writes matrix_multiplication_results.csv and creates a timing plot.
It uses timeit and may take several minutes because the implementations use
explicit loops. Reduce the sizes vector in cache_matrix_lab.m if needed.

Notes
-----
- The script checks numerical correctness against MATLAB's A*B.
- Results depend on MATLAB version, hardware, and system load.
- This is an implementation comparison, not a direct measurement of cache
  misses or cache behavior in isolation.
- Test these files with the MATLAB version used in your course before
  distributing them to students.
