Detect Change

Detecting a change in the signal value.

blockType: Detect Change

Path in the library:

/Basic/Logic and Bit Operations/Detect Change

Description

Block Detect Change determines that the current value of the input signal is not equal to the previous one.

  • The output signal takes the value true (1) if the current value of the input signal is not equal to the previous one.

  • The output signal takes the value false (0) if the current value of the input signal is equal to the previous one.

This block can only be used with discrete solvers.

Ports

Input

# IN_1 — Input signal
scalar | vector | the matrix

Details

The input signal is in the form of a scalar, vector or matrix.
