Hi. I have a class with a property values constructor looks like this

the constructor is called with a cell of variable lengths. now I need to store data arrays of different length in the property value for each element in the cell. the data will be called from a db with using a method. how can I do that? I tried something like

function obj = myClass(names) %names as cell,e.g. ('a','b'}

obj.values = struct(names)

end

However, this throws an error Conversion to struct from cell is not possible.

any idea how to work around that? if there is something fundamentally stupid about my approach, please let me know how to do that in a smarter way. cheers, Chris

Have a look at inputParser. My typical class constructor goes something like this:

function obj = myclass(varargin)
p = inputParser;
p.addParamValue('property1', [], @isnumeric);
p.addParamValue('property2', [], @ischar);
...
p.parse(varargin{:});  % edited this
fnames = fields(obj);
for n=1:numproperties
    obj.(fnames{n}) = p.Results.(fnames{n});
end
