Encapsulate

1.

Take the code I have provided and encapsulate it in a procedure. If you are not sure of the Maple syntax for procedures, read the book. Also, check out the examples from past homework solutions. You procedure should be called dft. It should take two arguments, an array of complex numbers (the signal) and an integer indicating the length of the array. It should return an array of complex numbers (the DFT).

2.

Test your procedure and make sure it yields the same result as the unencapsulated code.
