Inputs/Outputs

  • c2dcdb.png A

    A is a Hermitian matrix.

    The VI multiplies the first N rows and the first N columns of the upper or lower triangular component of A by X, where N is the number of elements in X. The number of rows and columns in A must be greater than or equal to N.

  • c1dcdb.png x

    x is an N–element complex vector.

  • c1dcdb.png y

    y is a complex vector of at least as many elements as x.

    The default is a vector with N elements, all equal to 0.

  • ci32.png matrix A type

    matrix A type specifies whether the VI uses the upper or lower triangular part of A for the calculation.

    2Lower Triangular—The VI uses only the lower triangular component of the input matrix for the calculation.
    3Upper Triangular (default)—The VI uses only the upper triangular component of the input matrix for the calculation.
  • ccdb.png alpha

    alpha is a complex scalar that scales A*x. The default is 1.

  • ccdb.png beta

    beta is a complex scale that scales y. The default is 1.

  • i1dcdb.png zhemv

    zhemv is a complex vector with the same number of elements as y that returns the result of alpha*A*x + beta*y.

  • 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.
