Inputs/Outputs

  • c2ddbl.png X —

    X is the 2D input array.

  • i2ddbl.png Yij=Xij/Max|X| —

    Yij=Xij/Max|X| is the 2D output array of the same size as X.

  • idbl.png max|X| —

    max|X| is the maximum absolute value in the input array X.

  • 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.

    • You can use this VI to normalize sequences within the range [–1:1]. This VI is particularly useful if the sequence is a zero mean sequence.

    Quick Scale 1D

    This VI calculates Y[i]=X[i]/Max|X| using the following equation:

    where s is the maximum absolute value in X.

    If X is an array of zeros, this VI returns max|X| as 0 and Y[i]=X[i]/Max|X| as an array of zeros.

    Quick Scale 2D

    This VI calculates Yij=Xij/Max|X| using the following equation:

    where s denotes the maximum absolute value in X.

    If X is an array of zeros, this VI returns max|X| as 0 and Yij=Xij/Max|X| as an array of zeros.
