Repeating Sequence Interpolated

Output discrete-time sequence and repeat, interpolating between data points

Library

Sources

Description

The Repeating Sequence Interpolated block outputs a discrete-time sequence and then repeats it. Between data points, the block uses the method you specify for the Lookup Method parameter to determine the output.

Data Type Support

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

  • Floating point

  • Built-in integer

  • Fixed point

  • Boolean

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

Parameters

Vector of output values

Specify the column vector containing output values of the discrete time sequence.

Vector of time values

Specify the column vector containing time values. The time values must be strictly increasing, and the vector must have the same size as the vector of output values.

Lookup Method

Specify the lookup method to determine the output between data points.

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.

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 Control Signal 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.
