MATLAB: How to determine which blocks support symbolic dimensions

Embedded Codershowblockdatatypetablesimulinksymbolic

When I try to run a Simulink model, the following error message is thrown:

'MyModel/Complex to Real-Imag' does not support symbolic dimensions propagation.

How can I check which blocks support symbolic dimensions?

This information can be found by executing the command:

>> showblockdatatypetable

It will open a table that summarizes all the datatypes that are accepted for each Simulink block.

Refer to the documentation bellow for more information regarding this function:

MATLAB: How to find out which Simulink blocks are not supported for code generation and what data types they support

The Simulink Block Data Type Support Table describes the data types that are supported by the blocks in the main Simulink and Fixed-Point libraries. The table also identifies blocks that are suitable for production code generation. You can view the table by typing the MATLAB command:

>> showblockdatatypetable

Alternatively, you can open an existing model or create a new model, then in the model window click on Help -> Block Support Table.

As of MATLAB R2017b, the list of Simulink blocks supported for code generation can be found on this documentation page:

MATLAB: How to list all the blocks in a model programmatically

To get a list of all the blocks in a model programmatically, please execute the following commands in the command prompt:

>> load_system('model_name')
>> bl = getfullname(Simulink.findBlocks('model_name'))

For more information on using this function please refer to the following documentation:

https://www.mathworks.com/help/simulink/slref/simulink.findblocks.html

The above "Simulink.findBlocks" command also finds the following types of blocks:

Blocks under masks.
Blocks that are commented out.
Variants of blocks.

But this does not find blocks that are present inside a library linked block. To find such type of blocks you have to create a "findOptions" object and set the "FollowLinks" option to "true".

To find more information about this please refer to the following documentation:
