Author Block Masks
Customize block appearance, user interface, and block diagram
A block mask is a custom user interface that you can create for a block. Mask a block to hide its underlying implementation details and provide a more user-friendly interface for setting parameters and options. Block masks are particularly useful for complex blocks or subsystems whose internal workings are not necessary for the user to understand or interact with directly. You can create a mask for a custom block and reuse it as unique instances of the block.
