irfft

irfft[input_rank: Int, input_type: DType, output_type: DType](input: NDBuffer[input_type, input_rank, origin], output: NDBuffer[output_type, input_rank, origin], n: Int, ctx: DeviceContext)

Compute the inverse real FFT of the input tensor.

Currently, only applies it to the last dimension.

Args:

input (NDBuffer[input_type, input_rank, origin]): Complex input tensor (NDBuffer).
output (NDBuffer[output_type, input_rank, origin]): Real output tensor (NDBuffer).
n (Int): Output signal size (if <= 0, computed as 2*(input.size(axis) - 1)).
ctx (DeviceContext): Device context.
