Whenever I try to move one of the library block to the blank page of simulink. Matlab gives me the following warning:

It also says: "Warning: Cannot find an exact case-sensitive match for the model or library name 'simulink'. Using the closest case-insensitive match: 'Simulink' at 'C:\Users\Dell\Documents\MATLAB\Simulink.slx'. Case-insensitive matching will be removed in a future release. Specify exact case instead."

Can someone help me out with this? Thank you!

Sincerely, a desperate student

在 MATLAB Online 中打开

Did you try checking if you had something shadowing the built-in function simulink?

which -all simulink

That command should list only files inside subdirectories of the toolbox\simulink directory under matlabroot. If it lists other files, rename those other files then restart MATLAB and try again.

Try renaming the file C:\Users\Dell\Documents\MATLAB\Simulink.slx to something other than Simulink.slx, like mySimulinkModel.slx. There may be a conflict between the simulink function in MATLAB and the name of your model that's confusing Simulink® when you try to add a block to the model.

Thank you for your respond! But it didn't work.. I also tried downloading it for the second time but it still gives me the same error.

Update: It did help! All I need to do was restarting the program after I renamed my file!

The solution by Steven Lord worked for me.

This issue occurred on 2017b, though I still used 2016b without a problem.

As Steven said, changing the "Simulink" file name to something else, then restarting the program worked for me.

The problem I had was that I named my file as Simulink.slx, so that created a conflict. I just renamed my file taking in consideration not to call it with names associated with Matlab´s files.
