IntEnumType

I see this error when trying to create an enumerated data type.

??? Error using ==> IntEnumType>IntEnumType.IntEnumType at 61 Not enough input arguments.

My script is called Color.m which is in a properly configured directory:

classdef(Enumeration) Color < Simulink.IntEnumType enumeration RED(1), GREEN(2), end end

I'm running MATLAB with Simulink ver R2010a.

I made sure to add the working directory to my matlab environment via addpath and save functions which executed fine. I'm starting to think that this is a bug.

1. What did you enter at the MATLAB command prompt to see this error?

2. What is the output of:

which -all Simulink.IntEnumType

1. What did you enter at the MATLAB command prompt to see this error?

I created a matlab script. In this case it was called Color.m and ran it.

2. What is the output of which -all Simulink.IntEnumType:

>> which -all Simulink.IntEnumType

C:\Program Files\MATLAB\R2010a\toolbox\simulink\simulink\+Simulink\IntEnumType.m % Simulink.IntEnumType constructor

I have even tried copying examples straight from Simulink's help documents and i still see this error. In this case i created a script called BasicColors.m which contains the following:

classdef(Enumeration) BasicColors < Simulink.IntEnumType

enumeration

Red(0)

Yellow(1)

Blue(2)

end

methods (Static = true)

function retVal = getDefaultValue()

retVal = BasicColors.Blue;

end

end

end

I run this and still get the same error which is:

??? Error using ==> IntEnumType>IntEnumType.IntEnumType

at 61

Not enough input arguments.

Other people on my team see the same thing. I almost think it is an issue with MATLAB R2010a.

Ok i figured out my problem. I did not need to run the MATLAB script. I can just drop a enumerated constant block in simulink and type in the enumerated name in the Output data type field in the Source Block Parameters. You also need to fill out the Value: field with classname.enum and it works!

I hope this helps out some newbs out there.
