Dear MATLAB users,

I have 5 different filters as 5 different radio buttons in MATLAB GUI. I made them into a button group and now when i click the each button the noise image is shown through the axes. But i want to set the button group in such a way to show only one filter (one image), when i click the particular radio button and others shouldn't be selected. So, I followed this (<http://stackoverflow.com/questions/2624875/how-to-pass-function-to-radio-button-in-a-button-group-created-using-guide-in-ma>) which is given by stackoverflow. But how do we "set" image in an axes. Thanks in advance

Regards,

In the radio button group callback you will need to either clear the axes or overwrite the data being displayed inside the object handle.

在 MATLAB Online 中打开

function uipanel1_SelectionChangeFcn(hObject, eventdata, handles)

if hObject == handles.gau

    mean = str2double(get(handles.mn,'string'));
    variance = str2double(get(handles.vn,'string'));
    fig_2 = handles.ii;
    fig_2 = im2double(rgb2gray(fig_2));
    fig_2 = imnoise(fig_2,'gaussian',mean,variance);
    axes(handles.ni);
    imshow(fig2);

like this, i have done for the rest of the buttons/filters. But its not functioning here in the button group. I have given the same command/code for each button/filter but its working there. I dont know, whts the problem?
