Just point at a cross-shaped tool at the top of the image window. That is the point picker tool. Then use that tool to point to a point on the image to read out the coordinate value of that point.

1.MATLAB is a commercial mathematical software produced by MathWorks, Inc. for algorithm development, data visualization, data analysis, and numerical computation of high-level technical computing language and interactive environment, including MATLAB and Simulink two major parts.

2. MATLAB is a combination of two words matrix&laboratory, meaning matrix factory (matrix laboratory). Is released by the United States mathworks company mainly face scientific computing, visualization and interactive programming of high-tech computing environment. It will numerical analysis, matrix computation, scientific data visualization and nonlinear dynamic system modeling and simulation and many other powerful functions integrated in an easy-to-use Windows environment for scientific research, engineering design and must be effective numerical computation of many scientific fields to provide a comprehensive solution, and to a large extent away from the traditional non-interactive programming languages (such as C. Fortran) editing mode, Fortran), representing the state-of-the-art in international scientific computing software.
