How to remove whitespace around subplots keeping margines for writing x/y labels and ticks?

I am generating a map in in MATLAB 2016b with 12 subplots. I am required to remove the whitespace between subplots for which I am using subplot_tight function. Apparently this function doesn't allow any space to put xlabel or y label, which is required.

In the attached image one can see how the X-axis and Y-axis ticklabels are getting omitted.

How to keep include white space to keep x-label and y-labels?

Below is my script,

margins=[0.0004,0.04];

for i=1:12

      if mod(i,2)==1
          subplot_tight(6,2,i, margins)        
          imagesc(A.data.Zone1)
          colormap(gca, brewermap([],'Blues'))

      elseif mod(i,2)==0
          subplot_tight(6,2,i, margins)        
          imagesc(B.data.Zone1)
          colormap(gca, brewermap([],'Greens'))
      end

      if i==11 || i==12
          set(gca, 'XTick', 1:1:12, 'XTickLabel',{'A','B','C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L'});

      else
          set(gca, 'XTickLabel',[]);
      end

      if ismember(i, [1:2:11])
          set(gca, 'YTick', 1:1:10, 'YTickLabel',{'M1','M2','M3', 'M4', 'M5', 'M6', 'M7', 'M8', 'M9', 'M10'});

      else
          set(gca, 'YTickLabel',[]);
      end

      set(gca, 'TickLength', [0.0001, 0.0001])
  end

For such tasks, i prefer using the OuterPosition property of axes. I.e.:

clearvars
close all
clc

f = figure;
for ii = 0:5
    for jj = 0:1
        ax = axes('Parent',f,...
            'Units','Normalized',...
            'OuterPosition',[jj/2 ii/6 1/2 1/6],...
            'XTickLabels','',...
            'YTickLabels','');
        xlim([0,400])
        ylim([0,200])
        ax.XLabel.String = 'xLabel';
        ax.YLabel.String = 'yLabel';
        hold(ax,'all')
        imagesc(rand(200,400))
    end
end

Feel free to substitute the ugly for-loops by cellfun and/or arrayfun.
