Computes the outer product of two vectors.

vector x

The first input vector.

This input accepts a 1D array of double-precision, floating point numbers or 1D array of complex double-precision, floating point numbers.

datatype_icon

vector y

The second input vector.

This input accepts a 1D array of double-precision, floating point numbers or 1D array of complex double-precision, floating point numbers.

datatype_icon

error in

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

datatype_icon

outer product

The outer product.

If one of the input vectors is an empty array, outer product is an empty array.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Algorithm for Calculating the Outer Product

This node calculates the output outer product using the following equation.

a i j = x i y j for { i = 0 , 1 , 2 , ... , n − 1 j = 0 , 1 , 2 , ... , m − 1

where

  • x is the input sequence vector x
  • y is the input sequence vector y
  • a is the 2D output sequence outer product
  • n is the number of elements in the input sequence vector x
  • m is the number of elements in the input sequence vector y

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
