Limit of Decreasing Plot Size in MATLAB

I use MATLAB R2021b. I have a 10x10 data array and I am using contourf function to plot the data. By default, MATLAB gives me a figure with 1120x840 pixels.

I know that I can use the command

set(gcf, 'position', [700, 700, 100, 100])

to decrease the size of the figure. And I get a figure with 200x200 pixels. I decided to shrink the value in the set function by half to get a 100x100 figure.

However, when I try to do

set(gcf, 'position', [700, 700, 50, 50])

, I got a figure with size 100x160. No matter how much further I decrease the value in the set function, the second dimension of the figure remained at 160 pixels. And there's no problem with the first dimension -- it can shrink with the value in the set function.

Does anyone know what's the problem here? My goal is to get a figure with 100x100 pixels.

Thank you very much for any advice!

Look at InnerPosition compared to OuterPosition

@Walter Roberson Thank you!

Hello everyone, I am the original poster. I think there is a minimum window size in both Windows and Mac operating systems. 100 pixels are smaller than the minimum windows size, so I cannot generate such a small figure.

This should be the answer for my question.

@Walter Roberson thank you very much for your hint. Your comment led me to this answer.

You should try these options with 'units', 'pixels':

set(gcf,'units', 'pixels','position', [700, 700, 50, 50])

Sorry, that doesn't help.
