How to use imwrite to save imshow(image01, [ ]) as a PNG file ?

So, I have an image file: image01.

When I use imshow to show the image, it will look different when I use limit: imshow(image01, [ ]).

When I use imwrite to write the image into a png file: imwrite(image01, "image01.png", "png"), the png file saved is the one when I dont use limit: imshow(image01).

I want to write the image shown when I use " imshow(image01, [ ]) "

Is it possible to do that using imwrite ? or do I have to use other method ?

First rescale the image before saving it

img_new = rescale(image01, 0, 1);
imwrite(img_new, "image01.png", "png")
