Custom defined data class not recognized

1 view (last 30 days)
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
obj@Simulink.Parameter();
% 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! :)
