Data Types

将特定的数据类型分配给信号和块参数，定义枚举

In models, data types determine the interactions between signals and block parameters. Numeric data types determine how a computer stores signals and parameters in memory and how a computer performs math operations. Other Simulink^®data types determine the structure or allowed values of signals and parameters.

为了模拟计算机硬件的数学行为，或从模型中生成有效的代码，您可以控制信号和参数的数字数据类型。您可以指定浮点，整数，固定点和其他数字类型。看Data Types Supported by Simulink.

Enumerated data types allow signals and parameters to use only a set of values that you specify. You can improve model readability by providing a meaningful name for each enumerated value. To use enumerations in Simulink, seeUse Enumerated Data in Simulink Models.

You can use bus types to group multiple signals or parameters together, which can improve model readability and ease model maintenance. See公共汽车的数据类型.

You can use string types to easily use strings in models.

数据类型过滤

Apply a filter to signals of different data types using standard Simulink® blocks. In this example, a signal with some noise is produced. This signal is then fed into a filter as a single precision data type and a standard double data type. The output from the filter for each signal is then compared and the error is displayed on the scope.
