Set the ‘Position’ property on the current figure (gcf). Specify the position as a vector of the form “[x0 y0 width height]”, where “x0” and “y0” define the distance from the lower-left corner of the screen to the lower-left corner of the figure. By default, the position is in pixels.
You can specify other units (inches, centimeters, normalized, points, or characters). For example:
You can also save a handle to your figure and set the Position property using dot notation:
f = figure;
f.Position = [10 10 550 400];
