Use image(), or imshow() (in the Image Processing Toolbox). If it's a floating point image, you need to use imshow(yourImage, []).

There is no difference to MATLAB between an "image matrix" and a "data matrix". It is all just data. Use imagesc(YourMatrix) or imshow(YourMatrix,[])

imagesc(yourmatrix)
will solve your issue.

By default, imagesc applies some weird colormap that's almost never what you want. Then you have to apply the correct colormap, like gray or whatever. That's why I avoid it and use imshow instead, which applies no colormap - it's just the normal gray scale colormap for a gray scale image.
