MATLAB: Library not loaded: @rpath/libmwhgbuiltins.dylib

Best Answer

It appears from the error that you included that MATLAB cannot find the "libmwhgbuiltins.dylib" possibly because Apple's System Integrity Protection software is preventing MATLAB from accessing the library file.

Below is a link to a workaround where you copy the library from the "matlabroot" location to the "/usr/lib/" folder.

The location of the library to be copied is:

>> fullfile(matlabroot, 'bin/maci64/libmwblas.dylib')

and it should be copied to

/usr/lib/

If you do not have access to that folder, you can place the library in a folder on the MATLAB path that you are working with, such as near the M file you are writing.

Reinstalling from a web-based download versus the ISO solved the problem.

MATLAB: Do I get a “Bundle#60 start failed” error using “imsegkmeans” on macOS 10.10 Yosemite

Please note that macOS Yosemite is not a supported operating system for the R2019a release. Based on the error message, it looks like the issue is caused by incompatible libraries. To resolve this, please upgrade to one of the supported operating systems listed in the link below.

If you cannot upgrade the OS, you can also try using the "kmeans" function from the Statistics and Machine Learning Toolbox. For example:

I = imread('cameraman.tif');
% kmeans requires numeric input, so convert to double
I = im2double(I);
idx = kmeans(I(:), 3);
% idx is a n x 1 vector, so reshape it to the size of the image
L = reshape(idx, size(I));
B = labeloverlay(I,L);
imshow(B);

Please find the documentation for "kmeans" linked below.
