The superclass definition is -
classdef calibration ... % Class name
< dynamicprops %% Superclass
% dynamicprops makes handle class
% Creation Properties
properties (SetAccess = immutable)
created = datestr(now, 'yyyymmddTHHMMSS');
author = getenv('username');
end
% Properties
properties
name = '';
end
% Dynamic Property
properties (SetAccess = protected, Hidden = true)
metaDynProp = [];
end
methods
val = get(obj)
set(obj)
end
% Methods
methods
function addCal(obj,calName,calVal)
% ADDCAL adds calibration to a cal object
% Determine calibration type
if isscalar(calVal)
caseNum = 1;
elseif isstruct(calVal) && length(calVal) == 4
caseNum = 2;
elseif isstruct(calVal) && length(calVal) == 6
caseNum = 3;
else
error('Invalid Calibration')
end
% Create Calibration
obj.metaDynProp.(calName) = obj.addprop(calName);
%obj.metaDynProp.(calName).SetAccess = 'private';
switch(caseNum)
case 1 % Scalar case
% Assign Methods
obj.(calName) = scalar;
%obj.metaDynProp.(calName).SetMethod = 'set@scalar';
%obj.metaDynProp.(calName).GetMethod = @scalar.get;
case 2 % Table case
% Assign Methods
case 3 % Map case
% Assign Methods
end
% Set Property
set(obj.(calName),calVal);
end
end
end
The subclass definition is
classdef scalar < calibration
properties
value = [];
end
% Methods
methods
function set(obj,value)
obj.value = value;
end
function value = get(obj)
value = obj.value;
end
end
end
I would like to have the functionality where a calibration can be added such as
x = calibration;
x.addCal('a',1);
Then when x.a is called, the output is 1. However, with the above implementation the output is a scalar object. Also, is there a way to prevent properties from being inherited?

Note that, for datetime formats
  • M corresponds to month
  • m corresponds to minute
  • s corresponds to second
  • S corresponds to fractional second
so
created = datestr(now, "yyyymmddTHHMMSS");
as a datetime would be
created = datetime("now", Format="yyyyMMdd'T'HHmmss")
created = datetime
