Usually it's possibe to open subsystems by "Open in new tab" by mouse action.

If theese tabs were not closed before saving the model it reopenes in same (all tabs open) way.

I want to create a script (e.g. for usage in pre-save callback), that closes all tabs except the first one.

The necessary command to access theese tabs was not yet found by me.

I'm using ML 2017B with matching Simulink-version.

I am not sure if this can be done through any of the MATLAB functions but it can be done using some external automation tools, which takes control of MATLAB and can perform various GUI actions.

在 MATLAB Online 中打开

I have just made a script that does exactly that !

Enjoy !

function preSave(system_name)
% preSave PreSaveFcn callback
    Blocks_List = find_system(system_name);
    % Since we close everything, need to open at least toplevel of
    % specified system in case it was not open already
    open_system(Blocks_List(1), "tab");
    % Index starts at 2 to not close toplevel
    for block = Blocks_List(2:end)'
        blk = block{:};
        % Bonus : Set Zoom factor to fit the window
        if strcmp(get_param(blk, 'BlockType'), 'SubSystem')
            set_param(blk, 'ZoomFactor', 'FitSystem')
        end
        if contains(blk,"/")
            if is_stateflow(blk) % Function that checks whether system is a stateflow : look it up if you want
                % sfclose considers chart names without toplevel
                % name in path, so we remove it
                sf_blk = extractAfter(blk,[system_name '/']);
                sfclose(sf_blk);
            else
                close_system(blk);
            end
        end
    end
    % Finally, set Zoom factor of top level
    set_param(Blocks_List{1}, 'ZoomFactor', 'FitSystem')
    clear Blocks_List block blk;
end
