Repeating Sequence Stair
Output and repeat discrete time sequence
- Library:
Simulink / 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]'. A value in
Vector of output values is output at each time interval, and
then the sequence repeats.

Parameters
Main
Vector of output values — Vector of output values
[3 1 4 2 1].' (default) | vector
Specify the vector containing values of the repeating stair sequence.
Programmatic Use
Block Parameter:
OutValues |
| Type: character vector |
| Values: vector |
Default: [3 1 4 2
1].' |
Sample time — Time interval between samples
-1 (default) | scalar
Specify the time interval between samples. To inherit the sample time,
set this parameter to -1. See Specify Sample Time
for more information.
Programmatic Use
Block Parameter:

| Type: character vector |
| Values: scalar |
Default: '-1' |
Signal Attributes
Output minimum — Minimum output value for range checking
[] (default) | scalar
Lower value of the output range that Simulink® checks.
Simulink uses the minimum to perform:
Parameter range checking (see Specify Minimum and Maximum Values for Block Parameters) for some blocks.
Simulation range checking (see Specify Signal Ranges and Enable Simulation Range Checking).
Automatic scaling of fixed-point data types.
Optimization of the code that you generate from the model. This optimization can remove algorithmic code and affect the results of some simulation modes such as SIL or external mode. For more information, see Optimize using the specified minimum and maximum values (Embedded Coder).
Note
Output minimum does not saturate or clip the actual output signal. Use the Saturation block instead.
Programmatic Use
Block Parameter:
OutMin |
| Type: character vector |
Values: '[ ]'|
scalar |
Default: '[ ]' |
Output maximum — Maximum output value for range checking
[] (default) | scalar
Upper value of the output range that Simulink checks.
Simulink uses the maximum value to perform:
Parameter range checking (see Specify Minimum and Maximum Values for Block Parameters) for some blocks.
Simulation range checking (see Specify Signal Ranges and Enable Simulation Range Checking).
Automatic scaling of fixed-point data types.

| Type: character vector |
Values: '[ ]'|

Default: '[ ]' |
Output data type — Specify the output data type
double (default) | Inherit: Inherit via back
propagation | single | int8 | int32 | uint32 | int64 | uint64 | fixdt(1,16,2^0,0) | <data type expression> | ...
Choose the data type for the output. The type can be inherited,
specified directly, or expressed as a data type object such as
Simulink.NumericType.

Lock output data type setting against changes by the fixed-point tools — Prevent fixed-point tools from overriding data types
off (default) | on
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 (Fixed-Point Designer).
