How can I add borders to my figure

How to add borders to my figures? I have tried many times to add them, but I could not. I am using MODIS data and the the functions to plot the figure are in following script:

    m_proj('lambert','lon',[45 85],'lat',[-01 50],'rectbox','on');
    m_grid;
    m_coast;
    m_gshhs_i('color','k');
    hold on;
    m_pcolor(lon, lat, AOD);
    colormap;
    shading interp
    hold on
    C=colorbar;

Thanks, Yazeed
