Hello Yang,
It seems like your installation might not have been completed fully. Try re-installing MATLAB. This comprehensive installation guide could be useful to you.
Further, from your snapshot, "libmwfl.dll" is often associated with errors related to Graphics Card Driver. To ensure if this indeed is the case, run the command -
matlab -softwareopengl
If MATLAB runs properly now, then update your Graphics driver to the most recent compatible version to solve your problem.
Hope this helps!

You can use other application(such as Uninstall Tool) to delete all the files of MATLAB and re-install it. And you also should do this:
Delete the user preferences directory.
In a File Explorer window, type the following into the address bar and then press Enter:
%appdata%
This will bring you to a folder called "Roaming" in the user account that you are currently logged in as. From here, open "MathWorks" and then "MATLAB".
Delete the folder corresponding to the MATLAB release you are removing, e.g. "R2014a." There may also be a licenses directory for the release in question, e.g. "R2014a_ licenses." Remove this folder as well.
Note: if you are an administrator performing this action for another user, you will need to do it from that user's Roaming directory, not the administrator's.
Remove the MATLAB Installer
Finally, delete the MATLAB installer you previously downloaded from you Downloads folder. This folder can change depending on your internet browser settings, but the default location is listed below:
C:\Users\<username>\Downloads
There will be a folder and EXE to delete for each MATLAB release. Please delete both and then re-download the installer from the MathWorks website.
Examples for the files are:
matlab_R20XXx_win64.exe
_temp_matlab_R20XXx_win64
Note: the XXx is a place holder for your specific release of MATLAB.
Hope that these can help you!
