Inputs

Name Description
a Specifies a vector or matrix of double-precision, floating-point or complex double-precision, floating-point numbers.
type Specifies the norm type. type is a scalar or string. If a is a matrix, type accepts the following values.

1 Computes the 1-norm.
2 (default) Computes the Euclidean norm.
inf Computes the max-norm.
'fro' Computes the Frobenius norm.
If a is a vector, type accepts the following values.

k Computes the k-norm. k is a positive integer. The default is 2.
inf Computes the maximal absolute value of a.
-inf Computes the minimal absolute value of a.

Outputs

Name Description
k Returns the norm type of a.

Examples

A = [1, 2, 3; 4, 5, 6; 7, 8, 9]
