Hi:

I met a problem with the display of the figure resolution between the figure plotted by Matlab and figure saved to my PC.

if I direct plot a figure with matlab, the resolution is definitely high.

but if I used the command: f = figure('visible','off'), and save the figure to my PC, the resolution is obviously lower than what I plotted with MATLAB.

I guess there might have somewhere to set the resolution, but I do not know how.

could anyway help me about this?

Thanks!
