  2. f-k transform:

    • Main code: "fk_main.m"
    • Function code: "fk_fun.m"

  3. t-p transform:

    • Main code: "tp_main.m"
    • Function code: "tp_fun.m"

  4. HRLRT transform:

    • Main code: "HRLRT_main.m"
    • Function code: "HRLRT_fun.m"

  5. F-J transform:

    • Main code: "Modified_FJ_Main.m"
