Syntax

tf = bdIsLoaded(bd)

Description

tf = bdIsLoaded(bd) returns whether the specified model, library, or subsystem saved in its own file is loaded.

Examples

Check Whether Models Are Loaded

Suppose you have two models named myModel1 and myModel2.

Check whether the models are loaded.

bdIsLoaded(["myModel1","myModel2"])

ans = 1×2 logical array
1	0

myModel1 is loaded, and myModel2 is not.

Input Arguments

bd — Model, library, or subsystem to check

model name

Names of one or more models, libraries, or subsystems saved in their own files that you want to check, specified as a string, string array, character vector, or cell array of character vectors.

Blocks, such as Subsystem blocks, cannot be loaded independently. Referenced subsystems can be loaded independently. For more information, see Create and Use Referenced Subsystems in Models.

Example: "myModel"

Example: ["myModel1","myModel2"]

Data Types: string | string array | character vector | cell array of character vectors

Output Arguments

tf — True or false result

1 | 0

True or false result, returned as a 1 or 0 of data type logical.

• 1 (true) — File is loaded.

• 0 (false) — File is not loaded.
