bdclose

Close any or all Simulink system windows unconditionally

Syntax

bdclose

bdclose(sys)

bdclose('all')

Description

bdclose closes the current system window unconditionally and without confirmation. Any changes made to the system since it was last saved are lost. To find out the current system, use gcs. If a model was only loaded, bdclose clears the model from memory.

example

bdclose(sys) closes the specified system window, discarding all changes.

bdclose('all') closes all open system windows, discarding all changes.

Close a System Without Saving

Open the vdp system. Then, close it without saving any changes.

open_system('vdp')
bdclose('vdp')

Input Arguments

System to close, specified as a character vector, string scalar, or cell array. To specify multiple systems to close, specify a cell array of system names.

Example: bdclose("vdp")

Example: bdclose({'vdp','f14'})

Data Types: char | string | cell

R2019b: Closing a window for a model hierarchy closes referenced models

Starting in R2019b, when you close a window for a model hierarchy by closing the top model, all referenced models that are not open in another window are also closed, which clears them from memory. To keep referenced models loaded in memory, use the close_system function and set the 'closeReferencedModels' argument to false.
