Use exportgraphics() to save the figure

exportgraphics(gcf, 'test.jpg', 'Resolution', 300)

saves currently active figure window.

MATLAB: 300dpi or 300dpcm

It's DPI, based on the documents provided by MathWorks here: https://www.mathworks.com/help/matlab/ref/print.html#inputarg_resolution

This is what they say:

"Resolution, specified as a character vector or a string containing -r and an integer value indicating the resolution in dots per inch. For example, '-r300' sets the output resolution to 300 dots per inch. To specify screen resolution, use '-r0'."

Doesn't say anything about dpcm, which would make unit conversion confusing actually...

If you want to use dpcm, you'd have to calculate and use the dpi equivalent.

MATLAB: Resolution requirements 300-600 dpi..

|Refer to the example code below.

x=(1:2:10)
y=(1:2:10)
plot(x,y)
size = [200 200];
res = 300;
set(gcf,'paperunits','inches','paperposition',[0 0 size/res]);
print('resized.tiff','-dtiff',['-r' num2str(res)]);

Here I have set the width and height to be 200. Resolution is set to 300dpi. To set the properties(“paperunnits” and “paperposition”) of the image, you could use the “set” function. “print” function is used to set the resolution to 300dpi.|
