HO, VO, PO, MO, LO, RO, OH, OV, HH, VV, PH, MV\n2. **Values** for specific polarization parameters:\n   - HV, VH, PV, MH, LH_RV, LV_RH\n\n### Example Input:\n```\nEnter angles for HO, VO, PO, MO, LO, RO, OH, OV, HH, VV, PH, MV (in degrees):\n30 60 45 30 90 120 45 60 90 45 30 60\n\nEnter values for HV, VH, PV, MH, LH_RV, LV_RH:\n0.5 0.5 0.3 0.3 0.4 0.4\n```\n\n---\n\n### Terms Explained\n\n1. **HO**: Horizontal Output Polarization\n2. **VO**: Vertical Output Polarization\n3. **PO**: Polarization Output at an arbitrary plane\n4. **MO**: Another polarization output state for comparison with PO\n5. **LO**: Left circular polarization output\n6. **RO**: Right circular polarization output\n7. **OH**: Horizontal Input Polarization\n8. **OV**: Vertical Input Polarization\n9. **HH**: Horizontal input and horizontal output polarization\n10. **VV**: Vertical input and vertical output polarization\n11. **PH**: Polarization input at an arbitrary angle and horizontal output\n12. **MV**: Mixed polarization input and vertical output\n13. **HV, VH**: Horizontal and Vertical cross-polarized input/output (used to represent cross-polarization effects)\n14. **PV**: Polarization at an arbitrary angle with vertical output\n15. **MH**: Mixed polarization input with horizontal output\n16. **LH_RV, LV_RH**: Represent left-hand circular to right-hand circular polarization interactions\n\n---\n\n### Output:\n\nThe program will output a 4x4 Mueller matrix based on the entered angles and polarization values.\n\n### Resources\n\n- Taken from Diffuse backscattering Mueller matrices of highly scattering media paper by Andreas H.
