Hi,
While trying to run Matlab 2018a code using "BM3D" downloaded from from http://www.cs.tut.fi/~foi/GCF-BM3D/ (the file is http://www.cs.tut.fi/~foi/GCF-BM3D/BM3D.zip I'm getting this errors.
tried almost every solution suggested on Matlab Answers Community with no success.
I'm using Xcode 9.2.
Invalid MEX-file '/Users/ericelharar/Documents/MATLAB/Eric_Pedro/BM3D/bm3d_thr.mexmaci64': dlopen(/Users/ericelharar/Documents/MATLAB/Eric_Pedro/BM3D/bm3d_thr.mexmaci64,
6): Library not loaded: @loader_path/libmat.dylib
Referenced from: /Users/ericelharar/Documents/MATLAB/Eric_Pedro/BM3D/bm3d_thr.mexmaci64
Reason: image not found.
Error in BM3D (line 342)
y_hat = bm3d_thr(z, hadper_trans_single_den, Nstep, N1, N2, lambda_thr2D,...

Hi, I'm having the exact same problem. Did you solve this by any chance? Thanks!

Hi,
By saying "I'm having the exact same problem" do you mean with BM3d?
if so, i wrote to Prof. Foi, who is associate Professor of Signal Processing at Tampere University of Technology, Finland, that developed the BM3D algorithm.
He was kind enough to send me a beta version that solves the problem with detailed instructions.
if you are interested send me an email and i will forward you the instructions and software.

Same here..
Does anyone happen to recall the last known good version of Matlab for BM3D? In a little bit of a pinch for getting comparison results done, so could well install an older version just for that.

Jaakko Lehtinen which Mac OS version are you using? I suspect that is more relevant than the MATLAB version for this purpose.

The original poster mentioned XCode 9.2, which is for MacOS 10.12.6+ onward, which is for Sierra; High Sierra needs XCode 9.3 or later.
MacOS Sierra was the release where Apple starting getting serious with System Integrity Protection, which turns off recognition of DYLD_DYNAMIC_PATH in some cases. This wasn't a MATLAB issue; it was an Apple issue. Individual programs could adapt to the Apple restriction, but the most obvious adaptation is to static link libraries instead of using DLL. For third-party packages such as BM3D, that would involve a change to BM3D rather than a change to MATLAB.

Sierra and High Sierra ignore DYLD_DYNAMIC_PATH in some cases, for security reasons. It is only intended to apply to some executables, but likely it is interfering.

tl;dr -- put copies of the library in /usr/lib

Hi, cp: /usr/lib/libmat.dylib: Operation not permitted I read there is a way to release this lock shell I try thIs before ?

Hi,
I've followed http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/ and managed to perform your advised solution -
sudo cp /Applications/MATLAB_R2018a.app//bin/maci64/libmat.dylib /usr/lib
now although the error massege starts with invalid mex I file it is a bit different and concludes
Symbole not found
