Build Kernel (G Dataflow)

Last Modified: June 25, 2019

Constructs a convolution matrix by converting a string.

The string represents either integers or floating-point values.

connector_pane_image
datatype_icon

kernel string

Coefficients that form the matrix.

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

kernel

Matrix converted from the input string.

You can connect this output directly to the kernel input in the Convolute node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Separators

The column separator is either a comma, a semicolon, or a blank space. The line separator is a linefeed character. For example, the string 1 1 1 1 1 1 1 1 1 produces a 3 × 3 matrix with all coefficients set to 1 as follows:

1 1 1
1 1 1
1 1 1
