Unable to add custom properties to an Excel Workbook

问题

Excel workbooks have a CustomDocumentProperties collection. This collection is of type DocumentProperties and has an Add method that I'm attempting to call from MATLAB.

If I call the invoke method on the collection I see:

>> workbook.CustomDocumentProperties.invoke
    Item = handle Item(handle, Variant, int32)
    Add = handle Add(handle, string, bool, int32, Variant(Optional))

I assume this means the Add method requires a string, boolean, int32, and an optional variant, and this matches with the Microsoft documentation for the Add method.

However, all combination of inputs I've tried to this function result in an error. For example:

workbook.CustomDocumentProperties.Add('MyProp', true, int32(1), true);

Results in the error:

Invoke Error: Incorrect number of arguments

If I supply 7 or more arguments then I get the error:

Error: Invalid number is arguments. This method can take maximum 6 arguments

If I supply anything other than a string as the first argument I get the error:

No method 'Add' with matching signature found for class 'Interface.2DF8D04D_5BFA_101B_BDE5_00AA0044DE52'.

Has anyone successfully used this function to add a custom property to an Excel workbook from MATLAB?
