how to use AliasType in Matlab Function (simulink)

Hi,

I would like to use an AliasType that I defined in a globalshare dictionary inside a matlab function.

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

What is the proper syntax for it?

A dumbed down example:

out=function foo(in1) %#codegen
%out needs to be of type 'my_float' which is a simulink alias type
%in1 is of type boolean
if in1
    out=my_float(5) %wrong syntax
else
    out=myfloat(4) %wrong syntax
end

Thank you

Hi,

From my understanding you are trying to use a Alias Type my_float in your Simulink model and generate code. The correct way to do this is as follows.

function out = foo(in1) %#codegen
%out needs to be of type 'my_float' which is a simulink alias type
%in1 is of type boolean
if in1
    out= 5;     
else
    out= 4;
end

And set the data type for the output block connected to out as you alias data type. This can be done as follows.

>> set_param('model_name/Out1','OutDataTypeStr','my_float')
