Computes the norm of Input Vector. Wire data to the Input Vector input to determine the polymorphic instance to use or manually select the instance.

Note You can use the Matrix Norm VI to calculate the matrix norm.

Inputs/Outputs

  • c1ddbl.png Input Vector —

    Input Vector is the real input vector. If Input Vector is an empty array, this VI sets norm to NaN.

  • cu16.png norm type —

    norm type indicates what type of norm you use to compute the norm. The default is 2-norm. If norm type is User Defined, this VI uses user defined norm as the norm type.

    11-norm
    22-norm (default)
    3Inf-norm
    4–Inf-norm
    5User Defined
  • cdbl.png user defined norm —

    user defined norm is the user defined norm type. The default is –1. This VI uses user defined norm as the norm type only if you set norm type to User Defined.

    user defined norm must be nonzero.

  • idbl.png norm —

    norm is the norm of Input Vector.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

    • This VI calculates norm using the following equations.

    1-norm ||X|| = |x0| + |x1| + … + |xn – 1|
    2-norm ||X|| = √(|x0|² + |x1|² + … + |xn – 1|²)
    Inf-norm ||X|| = maxi(|xi|)
    –Inf-norm ||X|| = mini(|xi|)
    User Defined ||X|| = ||x0|y + |x1|y + … + |xn – 1|y|1/y

    where X is Input Vector, y is user defined norm, and ||X|| is norm.
