Logic and Bit Operations

R2026b

Blocks for Boolean logic, signal comparison, edge detection, and bit manipulation, such as Logical Operator and Relational Operator

Use blocks from the Logic and Bit Operations library to implement decision logic and signal monitoring in your model. You can perform Boolean operations, compare signals, detect rising and falling edges, and convert between bit fields and integers.

To add blocks from this library to your model, see Add Blocks to Models.
