在 MATLAB Online 中打开

I think this should work?

I = imread('file_on_path.jpg') 
imagesc(I);

What do you mean by "squeezing" ? Are you talking about the colors, or about the image size, or about the axis proportions ?

Arun Badigannavar 2013-1-23

about the image size,,,the connections of simulink model which i am uploading are not visible and blocks are squeezed,,,and charecters which are there in the image re not clear

You can use image() without the Image Processing Toolbox. You can also use imagesc() but it applies some weird colormap by default that you'll most likely need to correct with colormap() function to a more appropriate colormap, like gray. image() applies a grayscale color map by default. With either one you can still call colormap to apply whatever colormap you want.
