ConditionalNSelect
This block copies one of its inputs to its output. The first (top), input is the control input; the remaining inputs are data inputs. The value of the control input determines which data input is copied.
Library
Routing
Description
This block specifies the signal routing based on the value of control signal as the first input. The remaining inputs are the possible signals to be copied to the output, they're labeled as case 1, case 2, case 3, based on the starting index 1 or 0 specified in block parameter. When control signal is not an integer, it's rounded to the proper integer value as selection index based on the rounding method defined in block parameter. For example if the control signal is 2, the "case 2" input is copied to the output. This block is suitable for performing switch-case decisions.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
nin | Number of inputs | Number of inputs to be copied to output. | Number | |
base | Base indexing | When 0 is selected, the index counts from 0, the 2nd input is labled case 0. When 1 is selected, the index counts from 1. | Scalar | 0 |
rule | Rounding method | Method for rounding the control signal to an integer, when the control signal is a non-integer. | String | 'int' |
externalActivation | External activation | Specifies whether the block receives an external activation or inherits its activation through its regular input ports. When External Activation is selected, an additional activation port is added to the block. By default, external activation is not selected. | Number | 0 |
