Let`s say that I have a image (100x500) (a simple 2D-array)
But I know that this image has a real-world size as 25.4 cm heigh and 210 cm wide, i.e. the proportion are different.
How can I plot this image with the (real-world) proportion and also showing the labels from (0...25.4 cm) x (0...210 cm) ?
Thanks in advance.

Use imresize():
[rows, columns, numberOfColorChannels] = size(yourImage)
newWidth = round(columns * (210/25.4))
yourImage = imresize(yourImage, [rows, newWidth]);
