Error loading library in gptoolbox\external\exactgeodesic\example1.m

[xjtu19]

when I ran this file: gptoolbox\external\exactgeodesic\example1.m, error occured:

example1 错误使用 loadlibrary 加载库 "E:\MATLAB_File\gptoolbox\external\exactgeodesic\geodesic_release.dll" 时出错 E:\MATLAB_File\gptoolbox\external\exactgeodesic\geodesic_release.dll 不是有效的 Win32 应用程序。

which can be translated as: Incorrect use of loadlibrary Error loading library "E:\MATLAB_File\gptoolbox\external\exactgeodesic\geodesic_release.dll" E:\MATLAB_File\gptoolbox\external\exactgeodesic\geodesic_release.dll is not a valid Win32 application.
