Is it possible to pass to a function the name of an axes component.

i.e.

function [high,low]=Autoscaleimage(handles,Image,n)
mn=mean(Image(:));
sd=std2(Image(:));
low=mn-sd;
high=mn+n*sd;
axes(handles.axes1)
imshow(img,[low,high]);

So sometimes I plot on axes2 and axes 3 etc, so can this be a function argument?

Hi Jason,

You can pass the 'axes' object to a function and plot on that specific axes

function [high,low]=Autoscaleimage(ax,Image,n)
%ax is the handle to 'axes' object
    mn=mean(Image(:));
    sd=std2(Image(:));
    low=mn-sd;
    high=mn+n*sd;
    axes(ax);
    imshow(Image,[low,high]);
end
