bdIsLoaded

Determine whether model, subsystem, or library is loaded

Syntax

tf = bdIsLoaded(bd)

Description

tf = bdIsLoaded(bd) returns whether the specified model, subsystem, or library is loaded.

Examples

Check Whether Model Is Loaded

Check whether the f14 model is loaded.

bdIsLoaded('f14')

ans =

  logical

   0

The function returns a logical scalar, 0, which indicates that the file is not loaded.

To load the f14 model, use the load_system function.

load_system('f14')

Check Whether Multiple Models Are Loaded

Determine whether the f14 and vdp models are loaded.

bdIsLoaded({'f14','vdp'})

ans =

  1×2 logical array

   1   0

The function returns a 1-by-2 logical array, which indicates that the first model in the cell array (f14) is loaded and the second model in the cell array (vdp) is not loaded.

To load the vdp model, use the load_system function.

load_system('vdp')

Input Arguments

bd — Name of model, subsystem, or library

string array | character vector | cell array of character vectors

Name of model, subsystem, or library, specified as a 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 Subsystem Reference.

Data Types: char | string | cell

Output Arguments

tf — True or false result

1 | 0 | logical array

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.

When multiple files are specified, the function returns a logical array with one entry for each file.
