plot - How can I set subplot size in MATLAB figure? -

i need plot 10 images together, using code results in small images :

img = rand(400,600);  i=1:10  subplot(2,5,i);   imshow(img);   title(['image ' int2str(i)]);  end 

as can see, images not use available space in screen. how can increase size, or decrease padding/margin between them?

thanks help.

i don't believe there easy way it. there 2 options:

first, use position part of subplot:

>> subplot(2,5, i, [l, b, w, h]) 

and calculate left, bottom, width, height.

or, handle of returned axis:

>> h(i) = subplot(2,5,i); 

and modify axis afterward.

>> set(h(1), 'position', [l, b, w, h] ); 

there number of pages give more detail, e.g., http://www.briandalessandro.com/blog/how-to-make-a-borderless-subplot-of-images-in-matlab/

[update]

the code below gives little more detail on can looking for. tad tedious. 0.95 , 0.02 give little padding. nothing magical. :-)

one other thing note encourage use "ii" index variable (or else) "i" defined sqrt(-1). convention not use "i" , "j" index variables (especially in matlab).

img = rand(400,600);   figure(1); clf(); hold on;  % width , height of figure lbwh = get(1, 'position'); figw = lbwh(3); figh = lbwh(4);  % number of rows , columns of axes ncols = 5; nrows = 2;  % w , h of each axis in normalized units axisw = (1 / ncols) * 0.95 axish = (1 / nrows) * 0.95  ii=1:10      % calculate row , column of subplot     row = floor( ii/(ncols+1) ) + 1     col = mod( ii-1, ncols ) + 1      % calculate left, bottom coordinate of subplot     axisl = (axisw+0.02) * (col-1)     axisb = (axish+0.02) * (row-1)      %  plot subplot     h= subplot('position', [axisl, axisb, axisw, axish] );      imshow(img);      title(['image ' int2str(ii)]);       pause end 

you have play make want. , "help" friend.
