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.
