x

A real vector.

Default: [0]{}

shift?

A Boolean that determines whether the DC component is at the center of FFT {x}.

TRUE The DC component is at the center of the FFT {x}.
FALSE The DC component is not at the center of the FFT {x}.

Default: FALSE

FFT size

The length of the FFT you want to perform. If FFT size is greater than the number of elements in x, this node adds zeros to the end of x to match the size of FFT size. If FFT size is less than the number of elements in x, this node uses only the first n elements in x to perform the FFT, where n is FFT size. If FFT size is less than or equal to 0, this node uses the length of x as the FFT size.

FFT {x}

The FFT of x.

error

A value that represents any error or warning that occurs when this node executes.
