mlx.core.fft.rfftfreq

rfftfreq(n: int, d: float = 1.0, stream: Stream | mlx.core.ThreadLocalStream | Device | None = None) → array

Return the discrete Fourier Transform sample frequencies for use with rfft() and irfft().

The returned array contains the non-negative frequency terms in the range [0, floor(n/2)].

参数:

• n (int) -- Window length.

• d (float, optional) -- Sample spacing. The default is 1.0.

返回:

The sample frequencies as a one-dimensional array of type float32.
