Interval Test Dynamic

Determine if signal is in specified interval

  • Library:
  • Simulink / Logic and Bit Operations

Description

The Interval Test Dynamic block outputs true (1) if the input is between the values of the external signals up and lo. The block outputs false (0) if the input is outside those values. To control how the block handles input values that are equal to the signal lo or the signal up, use the Interval closed on left and Interval closed on right check boxes.

Ports

Input

expand all

Upper limit of interval, specified as a scalar, vector, matrix, or N-D array.

Limitations

When the input signal is an enumerated type, the up and lo signals must be of the same enumerated type.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated

Input signal, specified as a scalar, vector, matrix, or N-D array.

Limitations

When the input signal is an enumerated type, the up and lo signals must be of the same enumerated type.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated

Lower limit of interval, specified as a scalar, vector, matrix, or N-D array.

Limitations

When the input signal is an enumerated type, the up and lo signals must be of the same enumerated type.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated

Output

expand all

Output signal indicating whether the input values fall within the specified interval. You can specify the Output data type as boolean or uint8.

Data Types: uint8 | Boolean

Parameters
