If m is your double matrix, use
imshow(m, []);
This works for any range of m - it doesn't have to be in the 0-1 range. Though if it already is in the 0-1 range, then you can omit the [] input argument to imshow().

You can use imresize():
resizedImage = imresize(originalImage, [500, 500]);
though be aware that there will be a different number of pixels in the new matrix and they won't have exactly the same values though they may be close.

Why might those be likely to be better? I never use those instead of imshow().
