placeFig, a FigureGrid command aware of screen size

A useful command to create a figure-grid of matlab figures tidily distributed across the screen

function placefig_Normalized(fig,m,n,k)

% PLACEFIG(fh,m,n,k) - puts figure fh in position k of a (m x n) array of figures on the screen.

% ------------------------------------

% placefig_Normalized(fig,m,n,k)

% ------------------------------------

% m x n picture matrix, set at location k, row-wise-counting

% k (m=2,n=3) x(n) y(m)

% 1 2 3 1 2 3 1 1 1

% 4 5 6 1 2 3 2 2 2

%

% Figure is resized to fit in the viewport at the indicated location k

%

% EXAMPLE: put figure to cover top half of the screen

% figure(31);

% placefig(31, 2,1,1);

%

% EXAMPLE: put figure to cover top/left quarter of the screen

% figure(31);

% placefig(31, 2,2,1);

%

% EXAMPLE: grid of 2x3 figures fill up first 4

% figure(31);figure(32);figure(33);figure(34);

% placefig(31, 2,3, 1);

% placefig(32, 2,3, 2);

% placefig(33, 2,3, 3);

% placefig(34, 2,3, 4);

%

% ------------------------------------

% Set-up settings calls (one argument)

% ------------------------------------

% placefig_Normalized(1)

% placefig_Normalized(0)

% placefig_Normalized(-k)

% ------------------------------------

% placefig_Normalized(-k) : Select monitor number k

% placefig_Normalized(1) : no margins top and bottom%

% placefig_Normalized(0) : reset margins top and bottom

%

% Issue about using pixels with monitor beyond nr 1:

% -------------------------------------------------

% If you specify a monitor other than primary one (-1), it will go to pixel units;

% If you connected|disconnected HDMI without restarting Matlab afterwards

% it will go out of screen.

% Solution 1: placefig(-1) will reset main monitor and overcome this but go to monitor 1

% Solution 2: restart matlab after you change the nr monitors connected

% rev.5.1, Massimo Ciacci, July 11, 2023

% note: better to place the figure immediately after creation, before plotting onto it, it works faster.

%

% note: since matlab is uncapable to refresh monitor status after plugging or unplugging monitors

% we cannot rely on pixel size that much, thereby we changed to normalized units, in the hope

% that the underlying Java scaler is able to keep up to date and avod tiny figures on Laptop displays.

%

% this however won't work with secondary monitors.

%

% =================================================================================================

% #### SUGGESTION: IN WINDOWS, DISPLAY SETTINGS, SET MAIN MONITOR = YOUR EXTERNAL LARGE SCREEN

% =================================================================================================

% If you have your laptop as main monitor accept the consequences (tiny figures on laptop screen)
