In a Simulink model, I am trying to identify what kind of block one of the blocks is. When I click on the block, a mfile opens up for editing, but

get_param(gcb,'BlockType')

returns 'SubSystem'. Seems wrong since a Subsystem Block is supposed to contain a block diagram. This block contains MATLAB code, so it seems to be one of 3 kinds of custom blocks: Fcn, Interpreted MATLAB Function, or MATLAB Function block. (1) What call to get_param tells exactly what kind of block this is, i.e. 'Interpreted MATLAB Function'? I want the block name that would be used in the documentation.

I have R2011b, but in earlier releases it seems these blocks had different names: Fcn, Embedded MATLAB Function, and MATLAB Fcn. In R2011b (2) was the Embedded MATLAB Function block renamed Interpreted MATLAB Function? I assume that the MATLAB Fnc block was renamed MATLAB Function Block, but let me know if that is wrong.

R2012b has not been released yet??

Sorry, I edited to say 2011b not 2012b.

Actually, the MATLAB Function block has been renamed to Interpreted MATLAB Function block; and the Embedded MATLAB Function block has been renamed to MATLAB Function block.

Here are the conditions you can use to perform your check:

BlockType=='MATLABFcn' for "Interpreted MATLAB Function" block
BlockType=='Subsystem' && MaskType=='Stateflow' for "(Embedded) MATLAB Function" block
BlockType=='Fcn' for "Fcn" block.

Thanks so much. In case it helps someone else trying to identify a block in order to look it up in the documentation:

1) Get an alphabetized list of *all* the block parameters, which might help identify the block:

orderfields(get_param(gcb, 'ObjectParameters'))

2) Block-specific properties for user-defined functions like the MATLAB Function Block are listed in http://www.mathworks.com/help/toolbox/simulink/slref/f23-20073.html#userdefinedfcns_lib_blkparams . For other kinds of blocks, http://www.mathworks.com/help/toolbox/simulink/slref/f23-30749.html
