RelationalOp
This block compares two input signals defined by the relational operator (parameter).
Library
Activate/LogicalOperations
Description
The RelationalOp block compares two input signals defined by the relational operator specified by block parameter. The comparision is made elementwise. The elements of the output matrix signal are either TRUE or False, represented by 1 and 0, respectively.
Supported relational operations are : "==", "~=", "<", "<=", ">" and ">=".
if the operator is "==", the result is TRUE if the two inputs are equal.
if the operator is "~=", the result is TRUE if the two inputs are not equal.
if the operator is "<", the result is TRUE if the first input is less than the second input.
if the operator is "<=", the result is TRUE if the first input is less or equal than the second input.
if the operator is ">", the result is TRUE if the first input is greater than the second input.
if the operator is ">=", the result is TRUE if the first input is greater or equal than the second input.
Parameters
| Name | Label | Description | Data Type | Valid Values |
|---|---|---|---|---|
rule | Operator | Relational operations supported by the RelationalOp block are : "==", "~=", "<", "<=", ">" and ">=". | String | '==' |
typei | Input datatype | Defines the datatype of the inputs.Supported types are : double, int32, int16, int8, uint32, uint16, uint8, boolean, inherit. | String | 'double' |
typeo | Output datatype | Defines the datatype of the output.Supported types are : double, int32, int16, int8, uint32, uint16, uint8, boolean, inherit. | String | 'double' |
