An easy solution will be just flip the labels. Run the following line
yticklabels(flip(yticklabels))
after creating the figure.

Can you explain what do you mean by "Though it flips the Y-axis values but does not start from X-axis"? Can you draw on this image to show the expected output?

After you display the image, try
axis xy

Did you try using YData in imshow():
yourImage = imread('peppers.png');
[rows, columns, numColorChannels] = size(yourImage);
imshow(yourImage, 'YData', [rows, 1]);
axis xy
