What images? .fig is a matlab figure...you have data in hand you plotted them and saved as .fig. What exactly you want to do?

Thanks for replaying, I have a code which creates several images. I could read the pixels from them before I saved them, but when I saved them with extension fig and jpg I couldn't read the pixels from them. Is there any way that I could read the pixels from the these images? I uploaded two images. Thanks

Don't save them as .fig files. Use imwrite() to save them as .PNG files. Otherwise you'll have to read in the figures with openfig() and then use getimage(), which is not as direct, plus .fig files are not readable by standard functions such as Photoshop or whatever.
