erfinv#

ivy.erfinv(x, /, *, out=None)[source]#

Compute the inverse error function.

Parameters:

x (Union[Array, NativeArray]) – Input array of real or complex valued argument.
out (Optional[Array], default: None) – optional output array, for writing the result to. It must have a shape that the inputs broadcast to.

Returns:

ret – Values of the inverse error function.

Examples

>>> x = ivy.array([0, 0.5, -1.])
>>> ivy.erfinv(x)
ivy.array([0.0000, 0.4769,   -inf])

Array.erfinv(self, /, *, out=None)[source]#

ivy.Array instance method variant of ivy.erfinv. This method simply wraps the function, and so the docstring for ivy.erfinv also applies to this method with minimal changes.

Parameters:

self (Array) – Input array with real or complex valued argument.
out (Optional[Array], default: None) – Alternate output array in which to place the result. The default is None.

Return type:

Array

Returns:

ret – Values of the inverse error function.

Examples

>>> x = ivy.array([0, -1., 10.])
>>> x.erfinv()
ivy.array([1.00000000e+00, 1.84270084e+00, 2.80259693e-45])

Container.erfinv(self, /, *, out=None)[source]#

ivy.Container instance method variant of ivy.erfinv. This method simply wraps the function, and so the docstring for ivy.erfinv also applies to this method with minimal changes.

Parameters:

self (Container) – The container whose array contains real or complex valued argument.
out (Optional[Container], default: None) – optional output container, for writing the result to.

Return type:

Container

Returns:

ret – container with values of the inverse error function.

Examples

With one ivy.Container input: >>> x = ivy.Container(a=ivy.array([1., 2., 3.]), b=ivy.array([-1., -2., -3.])) >>> x.erfinv() {

a: ivy.array([1.57299206e-01, 4.67773480e-03, 2.20904985e-05]), b: ivy.array([1.84270084, 1.99532223, 1.99997795])
