Getting the exact coordinates of some location on a map (longitude, latitude) using MATLAB

 I am stuck at finding the coordinates of a location on map from Google Earth, and I was told that MATLAB does very good job.

 I've read about Mapping Toolbox, and I did learn the basics for showing the maps, but couldn't:

1- Import the image map in MATLAB.

2- Analyze it to get the coordinates.

What I need exactly is the coordinates of the red points in the following picture:

Is that even possible?

Does your image have georeferencing information associated with it? If so, pix2latlon converts pixel locations to lat/lon coordinates. Or you can manually click around on an image and get coordinates of clicks with inputm.

First of all, Thank you for your answer.

Unfortunately, I don't have any information for this image, How can I get them? And is it possible to get a similar image using MATLAB so I can analyze it directly from there?

You could download a Landsat 8 image. Get the Level 1 GeoTIFF. Then the geotiffinfo and geotiffread functions should give you the georeferencing information you need. Without georeferencing information, there's no way to know where each pixel belongs in space.
