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.
