IMAQ BuildKernel VI
Owning Palette: FiltersInstalled With: NI Vision Development ModuleConstructs a convolution matrix by converting a string. This string can represent either integers or floating-point values.

Kernel String is a string listing the coefficients that form the matrix. |

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

Kernel is the resulting matrix converted from the input string. You can connect this output directly to the input Kernel in the IMAQ Convolute VI. |

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.

Details
The column separator can be 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 |
