Not enough input arguments

I believe to properly have set up the function. I don't think to miss anything, but still keeps giving me the error of not enough input arguments.

function AxialView(object,eventdata,ImgAx,S_s,S_c,S,S_a,sno,sno_a,Rmin,Rmax,shand,stxthand)

        if view == 'S'
            S_s = S;
        elseif view == 'C'
            S_c = S;
        end            
        view == 'A';

        Img = ImgAx;
        S = S_a;
        sno = sno_a;
        cla(hdl_im);
        hdl_im = axes('position',[0,0.2,1,0.8]);
        imshow(squeeze(Img(:,:,S,:)), [Rmin Rmax])

        if sno > 1
            shand = uicontrol('Style', 'slider','Min',1,'Max',sno,'Value',S,'SliderStep',[1/(sno-1) 10/(sno-1)],'Position', S_Pos,'Callback', {@SliceSlider, Img});
            stxthand = uicontrol('Style', 'text','Position', Stxt_Pos,'String',sprintf('Slice# %d / %d',S, sno), 'BackgroundColor', [0.8 0.8 0.8], 'FontSize', SFntSz);
        else
            stxthand = uicontrol('Style', 'text','Position', Stxt_Pos,'String','2D image', 'BackgroundColor', [0.8 0.8 0.8], 'FontSize', SFntSz);
        end

        caxis([Rmin Rmax])
        if sno > 1
            set(stxthand, 'String', sprintf('Slice# %d / %d',S, sno));
        else
            set(stxthand, 'String', '2D image');
        end

        set(get(gca,'children'),'cdata',squeeze(Img(:,:,S,:)))
        set (gcf, 'ButtonDownFcn', @mouseClick);
        set(get(gca,'Children'),'ButtonDownFcn', @mouseClick);
    end

The error comes to the line of Img=ImgAx;

which is completely unfair

@Stelios Fanourakis: how are you calling the function?

[Stelios Fanourakis]

@AxialView. It says it at the top

[Stephen23]

@Stelios Fanourakis: at the top you show us how you define the function, but not how it is called. I ask you to please show us how you are calling the function.

Basic ways of calling functions are explained in the introductory tutorials, which are highly recommended for all beginners:

This is the line code where I call the function AxialView:

VAxBtnhand = uicontrol('Style', 'pushbutton','Position', VAxBtn_Pos,'String','A', 'FontSize', BtnSz, 'Callback' , @AxialView);

Your comment shows that you have provided the function handle as a callback function to some GUI object. When you read the documentation for callback functions, it will inform you that by default only two arguments are provided to the callback function, which are called the source and event (commonly named src and evt inside the function definition).

Your function requires more than two input arguments - do you see the problem now?

If you wish to pass additional arguments then you will have to either:

• Read the section "Passing Additional Input Arguments" in the documentation that I linked to above.
• Use nested functions.

MATLAB does not just magically fill all of those input arguments with values.
