How do i get curvature values?

I am new to matlab. trying to get the curvature of my plot with the txt file (Has z,x,y axis). opened the 2D line curvature link, saved and opened as .m After that error prompted duplicate name, hence function name changed to LineCurvature2D1 instead of .m file name. when i run, command window only shows LineCurvature2D. How do i get the series of curvature number for my txt file?

Refer this: https://in.mathworks.com/matlabcentral/fileexchange/32696-2d-line-curvature-and-normals

      Vertices =load(''D:\Matlab\315 Big.txt');
      Vertices(:,1) = [] ;   % because all zeros     
      k=LineCurvature2D(Vertices) ;
