i need help, this code completely replicates my problem. is this an issue with just my computer? version of matlab? Or do I have a fundemental misunderstanding about what these numbers mean. I understand them to be in order, units away from the bottom left corner x dim, then y dim, then width and height. Help please

h = figure
plot(rand(10, 1))
h.Units= 'pixels';
h.Position = [3.2394e+03 524.2000 496.8000 340.8000]
%or if you dont have 2 monitors 
h.Position (1:2) = 100
axis square
% the numbers I got from the pictures uploaded using autohotkey to measure pixels are below
% I also measured using come calipers and the axes are the same size IRL which is consistant with
% autohotkey and 'axis square' 
BL = [1188, 1053];
BR = [1536, 1051];
TL = [1189, 705];
xLengthPx = BR(1) - BL(1)
yLengthPx = BL(2) - TL(2)
xLengthPx =
   348
yLengthPx =
   348
plotSize = getpixelposition(gca)
plotSize =
   65.5840   38.4880  385.0200  277.7520 % the output in pixels are nowhere near the real values 
   
plotSize = plotboxpos(gca) % on file exchange
plotSize =
    0.2380    0.1100    0.5591    0.8150 % the ratios of x and y lengths are nowhere near 1 as they 
    %should be
