datatype_icon

matrix

A square or rectangular matrix.

This input accepts a 2D array of double-precision, floating point numbers or 2D array of complex double-precision, floating point numbers.

datatype_icon

norm type

Type of norm that this node uses for the computation.

Name Value Description
2-norm 0 A 2 is the largest singular value of the input matrix.
1-norm 1 A 1 is the largest absolute column sum of the input matrix.
F-norm 2 A f is equal to Σ diag ( A T A ) where diag ( A T A ) means the diagonal elements of matrix ( A T A ) and A T is the transpose of A .
Inf-norm 3 A is the largest absolute row sum of the input matrix.

Default: 2-norm

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

norm

The norm of the input matrix.

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

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