Dot Product (G Dataflow)

A Boolean that specifies whether to reset the internal state of the node.

This input is available only if you wire a double-precision, floating-point number or a complex double-precision, floating-point number to vector x or vector y.

Default: False

First input vector.

This input accepts the following data types:

• Double-precision, floating-point number
• Complex double-precision, floating-point number
• 1D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers

When vector x is a 1D array of double-precision, floating-point numbers or a 1D array of complex double-precision, floating-point numbers, the number of elements in the first input vector must be greater than 0 and equal to the number of elements in the second input vector. Otherwise, the dot product is undefined, and the node returns NaN.

Second input vector.

This input accepts the following data types:

• Double-precision, floating-point number
• Complex double-precision, floating-point number
• 1D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers

When vector y is a 1D array of double-precision, floating-point numbers or a 1D array of complex double-precision, floating-point numbers, the number of elements in the first input vector must be greater than 0 and equal to the number of elements in the second input vector. Otherwise, the dot product is undefined, and the node returns NaN.

Length of each set of data. The node performs computation for each set of data.

This input is available only if you wire a double-precision, floating-point number or a complex double-precision, floating-point number to vector x or vector y.

Default: 100

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.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

The dot product.

Error information.

The node produces this output according to standard error behavior.
