You can also search:
- Model contents without loading the models into memory. On the MATLAB Home tab, in the File section, click Find Files. You can search a folder or the entire path. However, you cannot highlight results in models from the results in the Find Files dialog box the same way you do with project search. See Advanced Search for Files (MATLAB).
- A model hierarchy. In the Simulink Editor, on the Modeling tab, click Find. Select options to look inside masks, links, and references. This search loads the models into memory. See Model Explorer
- For variables, block parameter values, or search a model hierarchy and contents using more options, using the Model Explorer. This search loads the models into memory. Use the Model Explorer to search for variables in workspaces and data dictionaries, and variable usage in a model. See Edit and Manage Workspace Variables by Using Model Explorer
