Set its 'Value' to true and call its 'Callback' to the toggle button's callback:
function exampleTGL
%SCd
hFig = figure;
hPush = uicontrol('Style','pushbutton',...
'Units','normalized',...
'Position',[0.1 0.1 0.3 0.5],...
'String','Push Me!',...
'Callback',@Push);
hTog = uicontrol('Style','togglebutton',...
'Units','normalized',...
'Position',[0.5 0.1 0.3 0.5],...
'String','Toggle',...
'Callback',@tog);
function Push(src,evt)
set(hTog,'Value',true);
tog(hTog);
end
function tog(src,evt)
disp 'toggled'
end
end
