To specify the aspect ratio of a figure with a plot in MATLAB, you can use the “set” function.
width = 6; height = 8;
set(gcf, 'Units', 'inches', 'Position', [0, 0, width, height]); %set the width and height for the current figure

To save a plot with a specified resolution and aspect ratio in MATLAB, you can use the “print” function, which provides more control over the output quality and dimensions. The resolution can be passed as a parameter to the “print” function-
resolution = 300; % DPI
print(gcf, '-djpeg', ['-r', num2str(resolution)]);%save the current figure as a .jpeg image file
For more information about the “print” function and its parameters, refer to this link- https://www.mathworks.com/help/matlab/ref/print.html#:~:text=resolution%20%E2%80%94%20Resolution.
Hope this helps!
