Unrecognized function or variable 'planar_test_mex'. #26

Closed yushangdi closed 2 years ago

Hello,

I installed the matlabBGL package from Matlab add-ons, but I cannot use the planarity testing algorithm. I got:

Unrecognized function or variable 'planar_test_mex'.

Error in boyer_myrvold_planarity_test (line 41)
    is_planar = planar_test_mex(A,0);

I am using Mac with MATLAB R2021a. Does anyone know why this happens? Thanks!

I tried to download a pre-compiled version from here: https://dgleich.wordpress.com/2010/07/08/matlabbgl-osx-64-bit/

but then I got the following problem:

Invalid MEX-file '/Users/sy/Library/Application Support/MathWorks/MATLAB Add-Ons/Collections/MatlabBGL/matlab_bgl/private/planar_test_mex.mexmaci64': dlopen(/Users/sy/Library/Application Support/MathWorks/MATLAB Add-Ons/Collections/MatlabBGL/matlab_bgl/private/planar_test_mex.mexmaci64, 6): Library not loaded: @loader_path/libmex.dylib Referenced from: /Users/sy/Library/Application Support/MathWorks/MATLAB Add-Ons/Collections/MatlabBGL/matlab_bgl/private/planar_test_mex.mexmaci64 Reason: image not found
