Single Precision Converter Does not work with R2016B

I am using Matlab R2016b. I need to convert a Simulink model to single-precision. When I click Analysis-->Data Type Design --> Single Precision Converter, I got a blank window.

Then I tried to use command line:

>> report = DataTypeWorkflow.Single.convertToSingle("MyModel")

it instantly returns:

report =

Report with no properties.

Which I believe it didn't do anything, but no error or warning was displayed either.

Any help will be appreciated

Do you have an example in R2016b where you can test if the converter works as expected ?

in recent MATLAB ?

I wonder if you just happen to have an internal firewall that is blocking the tool from connecting to an internal process?

Thank you for the quick response.

No, I don't have this example in R2016B. I created a very simple model and tried Single Precision Converter, it doesn't work, but the it works fine with R2023B. Does this mean Single Precision Converter does not really function with R2016B? I notice this function was introduced with R2016B though

I'd contact MATLAB Product Support. They can tell you whether the Single Precision Converter in R2016B worked differently compared to R2023B.

I ran this in R2022b.

>> report = DataTypeWorkflow.Single.convertToSingle("f14")

report = 

Report with no properties.

However, I was able to launch the conver through "APPS", "Single Precision Converter" in R2022b.

It reported several incompatible blocks in "check compatibility" stage. The "Convert" and "Verify" stage didn't execute.

So I think that is why "report" is returned "with no properties". But of course, you have no way to tell if you can't open the converter through UI.

There are many places that could cause error in "check compatibility" stage, such as continus state, solver setting, etc. Thus, the "Convert" and "Verify" stage won't run. I suggest you check your model first. Once your model can generate code for a C99 embedded target, then you can try the report = DataTypeWorkflow.Single.convertToSingle() command again.
