nki.language.erf(x, *, dtype=None, mask=None, **kwargs)[source]#

Error function of the input, element-wise.

((Similar to torch.erf))

erf(x) = 2/sqrt(pi)*integral(exp(-t**2), t=0..x) .

Parameters:

  • x – a tile.

  • dtype – (optional) data type to cast the output type to (see Supported Data Types for more information); if not specified, it will default to be the same as the data type of the input tile.

  • mask – (optional) a compile-time constant predicate that controls whether/how this instruction is executed (see NKI API Masking for details)

Returns:

a tile that has erf of x.
