Assertion

Check for zero signal value.

blockType: Assertion

Path in the library:

/Basic/Sinks/Assertion

Description

The block Assertion detects 0 values in the input signal. If all elements are non-zero, the statement true (1) is executed and the block does nothing. If not, the block stops the simulation and returns an error message by default.

Ports

Input

# IN — input signal
scalar | vector | matrix

Details

Input for checking statements.
