Custom defined data class not recognized

Hello,

I'm trying to define my own data class in a package as described in Define Data Classes.

I've created the following folder structure:

D:\_rep\library\MATLAB_packages\+fwpck\@GlobalParam\

In that folder I created the file 'GlobalParam.m' with the following content:

classdef GlobalParam < Simulink.Parameter

%--------------------------------------------------------------------------

properties(PropertyType = 'double scalar')

ConversionFactor = 1;

end

%--------------------------------------------------------------------------

methods

function obj = GlobalParam(type, value, convFact, min, max)

% GlobalParam Class constructor

% call superclass constructor

[e-mail]();

% set properties

obj.DataType = type;

obj.Value = value;

obj.ConversionFactor = convFact;

obj.Min = min;

obj.Max = max;

end

end

end % classdef

I added the path 'D:\_rep\library\MATLAB_packages\' and tried the following code line:

>> globalParam1 = GlobalParam('single', 145.45, 0.34, 100, 200);

This results in the error

Unrecognized function or variable 'GlobalParam'.

What am I missing?

Any help would be highly appreciated. :)

Thanks

Christopher

That class is part of the fwpck package. You will need to call it using the package name or import the package.

y = fwpck.GlobalParam('single', 145.45, 0.34, 100, 200);

🤦‍♂️😂

Now it seems pretty obvious... I hadn't seen any example though.

Thanks a lot! :)
