Calculates the product of a scalar and a vector.

An integer that determines whether and how this node skips elements in **y** for the calculation.

The following table explains how this node behaves depending on the value of **y increment**.

Value | Behavior |
---|---|

y increment ≥ number of elements in y |
Uses only the first element in y. |

1 < y increment < number of element in y |
Uses only the elements whose indexes are multiples of the value of y increment. |

y increment = 1 |
Does not skip any elements in y. |

y increment = 0 |
Returns an error. |

y increment < 0 |
Reverses the order of the elements, and then uses elements that have indexes that are multiples of the value of y increment. |

**Default: **1

An integer that determines whether and how this node skips elements in **x** for the calculation.

The following table explains how this node behaves depending on the value of **x increment**.

Value | Behavior |
---|---|

x increment ≥ number of elements in x |
Uses only the first element in x. |

1 < x increment < number of element in x |
Uses only the elements whose indexes are multiples of the value of x increment. |

x increment = 1 |
Does not skip any elements in x. |

x increment = 0 |
Returns an error. |

x increment < 0 |
Reverses the order of the elements, and then uses elements that have indexes that are multiples of the value of x increment. |

**Default: **1

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an **error in** input and an **error out** output so that the node can respond to and communicate errors that occur while code is running. The value of **error in** specifies whether an error occurred before the node runs. Most nodes respond to values of **error in** in a standard, predictable way.

**Default: **No error

Vector of the same size as **y**.

If you set both **x increment** and **y increment** to 1, **daxpy** returns the result of **alpha** * **x** + **y** for the first *N* elements, and the value of the element in **y** with the same index for any remaining elements.

This output is available only if you wire a 1D array of double-precision, floating-point numbers to **x** or **y**.

Vector of the same size as **y**.

If you set both **x increment** and **y increment** to 1, **zaxpy** returns the result of **alpha** * **x** + **y** for the first *N* elements, and the value of the element in **y** with the same index for any remaining elements.

This output is available only if you wire a 1D array of complex double-precision, floating-point numbers to **x** or **y**.
