From the reference: https://www.mathworks.com/help/images/ref/imshow.html#bvmnrxi-1-DisplayRange
If you specify an empty matrix ([]), then imshow uses a display range of [min(I(:)) max(I(:))]. In other words, the minimum value in I is black, and the maximum value is white.
If I is data type single or double, then the default display range is [0, 1].
In my project, my I is a double (20 x 10), and I would like to show the minimum value in I is white, and the maximum value is black instead. Is there a way to do it?
Thank you.

Assuming that the image array A contains values in the range 0-1:
imshow(1-A)
