how can I fix this error code in cbir using wavelet transform and color histogram ?

I have a project of CBIR (Content Based Image Retrieval) using wavelet transform and color histogram. I perform re-experiment from Singha and Hemachandran research. I have tried to code it, but when an image was added in database, there was an error. The error message states :

Error using database/fastinsert (line 222)
Cell array or struct should not contain vectors

Error in koneksidbEkstraksi (line 11)
fastinsert(conn, 'ekstraksifitur', colciri, rowciri);

Error in metode_ekstraksi (line 157)
koneksidbEkstraksi(A, H, V);

Error in tambah>btn_tmbhcitra_Callback (line 361)
        metode_ekstraksi(input);

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in tambah (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in
@(hObject,eventdata)tambah('btn_tmbhcitra_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

I think it was caused by algorithm of extraction code. I have attached the m-file of algorithm code. It was named metode_ekstraksi.m . Before that, I've also attached the m-file of database connection for result of extraction. It was named koneksidbEkstraksi.m. I hope someone can help me to solve this problem.

Thank you.
