tr=triangulation(whitevol.faces,whitevol.vertices);
figure('color','w'), h=trimesh(tr); axis equal
% now write to STL
stlwrite(tr,'cranialSegment.stl');
I'm trying to compute and export a .stl file using the code above. However I keep getting the errors mentioned below. What does this error mean? I was able to export the 3D data before just fine, but for some reason I am now getting these errors.
Error using fileparts (line 58)
Input must be a row vector of characters, or a string scalar, or a cellstr, or a string
matrix.
Error in stlwrite (line 70)
path = fileparts(filename);
Error in test3 (line 133)
stlwrite(tr,'cranialSegment.stl','binary');

You appear to be trying to use MATLAB's stlwrite function, but the error messages suggest you are using this one from the File Exchange instead.
https://www.mathworks.com/matlabcentral/fileexchange/20922-stlwrite-write-ascii-or-binary-stl-files
To use MATLAB's function, remove the File Exchange function's folder from you MATLAB Path (or delete it).
If you want to use the file exchange function, follow the syntax requirements for that function.
function stlwrite(filename, varargin)

Thank you.
I had the same issue because of the stlwrite function loaded from the exchange. Solved my issue after removing it.
