MATLAB: Imshow border tight for subplot

Question

i can hide the grey border around the figure with setting;

iptsetpref('ImshowBorder','tight');
figure;Image = rand(1000,1000);
imshow(Image,[]), colormap jet;

How can i do the same if i am using subplot! iptsetpref doesnot seem to have any effect in subplot.

iptsetpref('ImshowBorder','tight');
figure;
subplot(1,2,1)
imshow(Image,[]), colormap jet;
subplot(1,2,2)  
imshow(Image,[]), colormap jet;

Answer 1

Use subplott to generate axes handles for each individual subplot

h = subplott(3,3);
imshow('cameraman.tif','parent',h(6));
imshow('pout.tif','parent',h(2));

Note, the images will not be tight in both dimensions unless the figure is turned into the correct shape manually and all images are the same shape.

E.g.:

set(gcf,'units','pix')
set(gcf,'position',[200 200 800 800])

With the figure from above. Where subplott.m is:

function [hA] = subplott(nr,nc)
%function to return a figure handle and axes handles for tight subplots
%



%Inputs:
%  r: number of rows
%  c: number of columns
%
%Outputs:
%  hA: axes handles to subplots (styled order, i.e. rows first then columns)
%

      rlow = flipud(cumsum(rspan(ones(nr,1)))-rspan); %lower edge
      clow = cumsum(cspan(ones(nc,1)))-cspan;
      [rg cg] = meshgrid(1:nr,1:nc); %grids
      hA = zeros(na,1);
      figure;
      for ii = 1:na
          pos = [clow(cg(ii)) rlow(rg(ii)) cspan rspan]; %positions
          hA(ii) = axes('units','norm','outerposition',pos,'position',pos); %build axes
      end 
  end
