FourierTransform: Vector is missing spacing/commas

[Abelpalmer22]

Typo Details:

Are these supposed to have commas between the entries? Right now it looks like multiplication

Suggested Fix:

Just add commas between them

Typo Details:

Commas should go between entries in the vector

Suggested Fix:

Commas in the vector
