uncommented comments and invalid imports in class def in the file DataTime.m

[babaq]

just found that the file license header is not properly commented, and lots of

import yaml.*

before every function defined in the DataTime class.

i am not sure this kinds of import is valid, but my Matlab R2016a complaints that this is not the valid syntax, may be it should be moved into the function definition.

I suspect that you are getting errors because the package is not on your path?

I had the same issue, solved it by adding the implementation of doFun:

    methods (Access = private)
        function this = doFun (this,o, val)
            import yaml.*;
            if isa(val,'DateTime') && isa(this,'DateTime')
                this.serialDate=o(this.serialDate, val.serialDate);
            elseif isa(val,'DateTime') && not(isa(this,'DateTime'))
                val.serialDate=o(this, val.serialDate);
                this = val;
            elseif not(isa(val,'DateTime')) && (isa(this,'DateTime'))
                this.serialDate=o(this.serialDate, val);
            else
                this.serialDate=DateTime(o(this, val));
            end
        end
        
        
    end
    
end

Code is I think from here: https://github.com/ziyuw/rembo/blob/master/src/utils/yamlmatlab/DateTime.m
