Repeating Sequence Stair

Output and repeat discrete time sequence

Library

Sources

Description

The Repeating Sequence Stair block outputs and repeats a stair sequence that you specify with the Vector of output values parameter. For example, you can specify the vector as [3 1 2 4 1]', which produces the following stair sequence:

Data Type Support

The Repeating Sequence Stair block outputs signals of the following data types:

  • Floating point

  • Built-in integer

  • Fixed point

  • Boolean

  • Enumerated

For more information, see Data Types Supported by Simulink in the Simulink® documentation.

Parameters and Dialog Box

The Main pane of the Repeating Sequence Stair block dialog box appears as follows:

Vector of output values

Specify the vector containing values of the repeating stair sequence.

Sample time

Specify the time interval between samples. To inherit the sample time, set this parameter to -1. See Specify Sample Time for more information.

The Signal Attributes pane of the Repeating Sequence Stair block dialog box appears as follows:

Output minimum

Specify the minimum value that the block should output. The default value is [] (unspecified). Simulink software uses this value to perform:

Output maximum

Specify the maximum value that the block should output. The default value is [] (unspecified). Simulink software uses this value to perform:

Output data type

Specify the output data type. You can set it to:

  • A rule that inherits a data type, for example, Inherit: Inherit via back propagation

  • The name of a built-in data type, for example, single

  • The name of a data type object, for example, a Simulink.NumericType object

  • An expression that evaluates to a data type, for example, fixdt(1,16,0)

Click the Show data type assistant button to display the Data Type Assistant, which helps you set the Output data type parameter.

See Specify Block Output Data Types for more information.

Lock output data type setting against changes by the fixed-point tools

Select to lock the output data type setting of this block against changes by the Fixed-Point Tool and the Fixed-Point Advisor. For more information, see Use Lock Output Data Type Setting.
