Answer 1

I know of three ways:

1. Alias types using Simulink.AliasType
2. Custom numeric types using Simulink.NumericType
3. Structure types using Simulink.Bus

You can also define a Custom Storage Class if you want to introduce a new storage class specification. (examples of storage classes are static, volatile, etc.)

Thank you for giving info @kaustubha

Don't you also have to register the respective data type via sl_customization.m?

[Kaustubha Govind]

Yes, I do believe you need to do that, but I was only listing the several different techniques available. For more detailed information, the documentation should be consulted.
