# Matrix Update (General » Rank-1 Update with Conjugation) (G Dataflow)

Calculates the rank-1 conjugated update of a general matrix.  ## x

N-element vector. ## y

M-element vector. ## A

General matrix.

A must have dimensions greater than or equal to N × M. If A is an empty matrix, this node initializes A to be an N x M matrix with all elements set to 0. ## 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 ## alpha

Scalar that scales x * y H, where y H represents the conjugate transpose of y.

Default: 1 ## zgerc

Matrix of the same dimensions as A.

For elements in the first N rows and M columns, zgerc returns the results of alpha * x * y H + A, where y H represents the conjugate transpose of y. For any remaining elements, zgerc returns the value of the element in A with the same index. ## error out

Error information.

The node produces this output according to standard error behavior.
