Function Documentation

ty af::norm	(	const array &	in,
		float	p = af::NaN
	)

Matrix or vector norm.

Some options require ArrayFire Pro.

  
// compute norm of vector x
array x = randu(1e5);
print(norm< float >(x));
  

Parameters

[in]	in
[in]	p	type of norm: p == Inf returns max(abs(in)) for vectors, infinity norm for matrices p == -Inf returns min(abs(in)) for vectors, not supported for matrices p == NaN (default) returns Euclidean norm for both vectors and matrices p (anything else) returns p norm of the input

Note

if p is 2 and the input is vector, ArrayFire Pro license is required.
