How to display blocks of a custom library in the Simulink library browser?

I have started working on a Simulink library. I followed the instructions provided in MATLAB help and managed to create the library that I wanted. Everything works as it is supposed to, i.e. the library name is displayed in the library browser, I can open it (by right clicking on it), drag the blocks to my models and use them. However, the blocks that are in the library are not displayed in the right hand side of the library browser. Does anyone know how can I possibly display them?

Hi Mihail,

hmm, never heard this: whenever I had a user being able to write the slblocks function, the content of the library also appeared. Perhaps this would be a question to ask the technical support ...

Thank you for your replies. The answer to Ms. Govind's questions are 1). Yes. All of the blocks are subsystems. 2). Yes. They all have masks and all have parameters.

Also, my slblocks function looks like (I tried both 1 and 0 for Browser.IsFlat and also tried deleting the line completely):

function blkStruct = slblocks
  % Specify that the product should appear in the library browser
  % and be cached in its repository
  Browser.Library = 'DrivetrainLibrary.mdl';
  Browser.Name    = 'Drivetrain Library';
  Browser.IsFlat  = 1;% Is this library "flat" (i.e. no subsystems)?
  blkStruct.Browser = Browser;

Could you try changing that line to:

Browser.Library = 'DrivetrainLibrary';

You shouldn't specify the .mdl extension.

As Titus mentioned, if you have your slblocks.m configured, the blocks should show up. Are your blocks all subsystems? If yes, do they have masks, and do the masks have any parameters?

I have the same problem, but it only recently appeared when we changed from using 2014b, where they do appear, to 2017a, where they do not appear, with no change to the slblocks.m file. What's going on?
